for all the latest updates on world events.
On the subject of mercenaries, Saif al-Islam says "half the Libyan people are black", and that "our foreign minister is black. Is he a mercenary? Not every black person is a mercenary."
On the events in Benghazi, Saif al-Islam says the army is not used to crowd-control, and that what happened in the city was a vicious circle in which nervous soldiers fired on people, and the people became angry, which triggered more clashes and more deaths and more anger, BBC Arabic reports. He added the coverage of state media of the events was a failure.
More from Saif al-Islam, who was speaking in an exclusive pre-recorded interview shown on al-Arabiya TV: He describes what is happening in Libya as an "armed insurrection" which will end; he also says Misrata will return to state control, saying it is a city of 550,000 people which "won't cave in to 40 or 50 armed people", BBC Arabic Service reports.
Col Gaddafi's son, Saif al-Islam, says eastern Libya cannot break away from the rest of the country, Reuters reports.
In neighbouring Tunisia, the interior ministry has announced traffic and pedestrians are banned on Avenue Habib Bourguiba, one of the Tunisian capital's main thoroughfares, following violent protests there on Saturday afternoon, AFP reports. The ban is in place from 1800 (1700 GMT) on Saturday until midnight on Sunday.
Mercenaries have opened fire on protesters in Misrata, about 200km (125 miles) east of Tripoli, al-Arabiya TV reported in a screen caption a few minutes ago, BBC Monitoring reports.
Phil Johnson, who says between 50 and 100 other expats are at the oil facility, adds they are beginning to run out of food, but are worried about leaving: "We dare not go west towards Tripoli because we've heard of Libyan colleagues actually just the other day, they were shot and killed just driving down the road trying to get to Tripoli."
There's growing concern for up to 400 Britons who've been working in the Libyan oil fields amid reports that Col Gaddafi is arming his civilian supporters. Phil Johnson, who's from Lancashire, is stuck in Marsa el Brega - a settlement halfway between Benghazi and Tripoli. He says he's been getting regular updates from his wife back home in England - otherwise he remains in the dark about exactly when he will be able to make his escape: "We're actually learning more off our families than any official contacts, plus we're hearing conflicting information. Our contact people in Tripoli just yesterday said to me I would rather you come to Tripoli than go to Benghazi, and then my wife rang and said: 'No no, no, it's still horrific in Tripoli, round the airport, it's Armageddon'."
More on the clashes in Sabratha: The al-Khuweildi al-Humaidi battalion opened fire in an area along a strip on the Mediterranean cost between the cities of Sabratha and Surman, the online version of Quryna reported, quoting its correspondent there, Reuters says. It did not specify the circumstances of the shooting and who the victims were.
Barq, a Libyan opposition network on Facebook, has this snap: "Zawiya residents have denied reports on Libyan State TV of dialogue under way between them and the Gaddafi regime." It goes on to say that Gaddafi is "desperate to divert attention from the massacres he is committing" and that such broadcasts on state TV show that "his days are numbered".
UN Security Council meets in urgent session to consider sanctions against Libya, AP reports.
Dozens "severely wounded" after pro-Gaddafi battalion opens fire on protesters near Sabratha, west of Tripoli, according to Quryna newspaper, Reuters reports.
Dima Khatib, an Arab journalist
tweets: "I hear a few intellectuals speaking from liberated areas of Libya, concerned, saying they don't want foreign hands to intervene."
More from Nesrine Malik of the Guardian: "From the beginning of this entire wave of protests, the UN and the US, the West in general, have been playing catch-up in terms of policy, in terms of rhetoric, and in terms of actual action. And what makes it more difficult is that Libya is a little bit more of a pariah state than Egypt and Tunisia, and Gaddafi is used to being a pariah and is used to being isolated, so there is not really much influence that anybody can have on him."
Nesrine Malik, Middle East commentator for the Guardian newspaper, says of the sanctions they are a case of closing the stable door after the horse has bolted: "There has been relationships with Gaddafi in the past few years, the arms are already there, the weapons have already been sold to him, and therefore sanctions now seem to be a bit of a late option to take," she tells BBC World TV.
tweets: "There is a very uneasy quiet in Tripoli right now. Almost all security forces have retreated to somewhere... Wonder what they're up to."
The BBC's Barbara Plett at the UN says much of the negotiations currently going on over Libya are focusing on the proposals relating to the International Criminal Court, specifically referring Libya to the court for an investigation into war crimes. Some states here are completely opposed to that, and some have questions about the language, our correspondent says.
Glenn in Manchester, UK writes: "For once, the more powerful nations have a moral duty to intervene militarily. If they hesitate and prevaricate too much, there is the makings of a genocidal backlash against the protestors."

tweeted earlier: "Expect poss desperate measures now from Gaddafi + entourage as whats left of his regime appears cornered in NW #Libya"

State TV news bulletins have stopped. One striker, asking not to be named, told Reuters: "We are on strike demanding an end to all the pressure and to stop the censorship, and to allow us to work freely... We will not accept restrictions anymore."
in Tripoli tweets: "Even #Gaddafi's "voluptuous Ukrainian nurse" deserted him http://ow.ly/1s4UfO #Libya #Feb17"
More from Hassan Mushaima, who told the BBC the royal family in Bahrain had failed to fulfil promises it had made to the people and that he wanted genuine democratic reform that could turn Bahrain into a constitutional monarchy: "[At] different times they have promised us [things], but they did not go with their words. If the societies agreed and the nation agreed for the... constitutional monarchy, a REAL one, that's something else. If they are really honest..., they are going to do it."
We have more on what leading Shia politician Hassan Mushaima, whose return to Bahrain we reported earlier, said when he arrived at the airport in Manama. He told the BBC he wanted to be part of a unified opposition: "...Demands - that's up to the people on the ground who died there and who faced everything just to get their demands. So that's why I'm with the people and also I am with all the societies to sit and also to discuss all the demands and to say [speak with] one word, not different words and not different demands."

In the latest Libyan diplomatic defection, the Libyan ambassador to Somalia, Issa Ashur, has announced he is "joining the revolution", in protest at the Gaddafi regime's use of violence against demonstrators.

More on the capture of Brig Gen Abu Bakr Ali in Misrata (1414): The statement on Libyan TV may refer to a video posted on Facebook on the same day, captioned "Brigadier-general from the Gaddafi regime who was captured by the brave sons of Misrata. Brigadier-General Abu Bakr Ali Mohamed al-Qadhafi", BBC Monitoring reports.

More from the BBC's Kevin Connolly on the situation in Benghazi where Libyan rebels are trying to run the city as normal (1231 entry): "But this is an abnormal reality.

in Bahrain tweets: "Thousands of ppl r here at the rally #bahrain #feb14 #lulu http://twitpic.com/43yi3z"
More on the British charter plane that has landed in Tripoli: It is likely to be the last charter flight organised by the British government. All Britons remaining in Tripoli have been urged to board the plane.
The latest update from the Foreign Office says the Boeing 737 charter flight which has been sent to pick up Britons in Tripoli arrived just before 1345. The plan is that it will stay on the tarmac for as long as possible. There is space for 148 people on board. Apparently it can stay there for a maximum of six hours - but it isn't clear whether it will be allowed to do so.
Libyan state TV has just put out an urgent screen caption saying Brig Gen Abu Bakr Ali Mohamed, a senior army officer, was captured by terrorist gangs in Misrata for "electronic support", which is assumed to mean the video footage of his plea to Col Gaddafi, reports BBC Monitoring.
Thanks for joining us on the BBC's live page covering events in Libya and further afield in the region. To recap on Saturday's main developments so far, latest reports from the Libyan capital, Tripoli, say the city is quiet after a night of sporadic gunfire; in Bahrain a leading opposition figure has returned from self-imposed exile.
A woman who left Libya with her parents last week and hopes her boyfriend can get an American flight out later on Saturday told the BBC the scenes she had encountered had been very frightening: "When the mob surged and we didn't realise at the time that they were escaping the police - we thought they were angry and surging towards us because there was chanting and stones being thrown. We had to grab on to the railings because we thought we were going to get taken away with it. But luckily it didn't happen; but the things we saw, I mean the police hunted those poor people like dogs with sticks and shouting - something I've never seen or want to see again in my life."
Turkish Prime Minister Recep Tayyip Erdogan has come out against imposing sanctions on Libya. "You cannot secure world peace by resorting to sanctions in each and every incident," he said in a televised public speech in Istanbul.
Public and private banks have re-opened many branches across Benghazi in a sign of returning normality, Reuters reports.
More from Bahrain on the return of opposition leader Hassan Mushaimaa. He was welcomed by supporters at the airport, where he told the BBC that he wanted genuine democratic reform that could turn Bahrain into a constitutional monarchy.
Here's a name we may hear more of: Muhammad al-Senussi, the heir apparent in Libya's overthrown monarchy. Interviewed by AFP, the successor to King Idriss praised the rebels in his homeland and urged the ejection of Col Gaddafi. The Libyan royal family was ousted by the colonel in 1969, and forced out of the country altogether in 1988. Does Mr Senussi want to regain the throne for his family? "I see myself as a servant to the Libyan people," he says. "They will decide what they want. My goal is to serve my people as much as I can."
Libya, again, is our focus for this Live Page. That said, it is worth mentioning that there are reports of rallies today not just in Bahrain but in Yemen, Tunisia and Algeria. In Yemen, leaders of two of the most important tribes abandoned the president and joined the opposition movement, AFP reports.
We are beginning to see reports on Twitter of a pro-democracy rally in Bahrain, currently heading towards the prime minister's office.

"There was clear agreement that the actions of the Libyan regime were totally unacceptable and that brutality and intimidation would not be tolerated," the spokesman said.
Mohamed, who lives in the Libyan city of Misurata, has told the BBC it is under the control of the opposition but the situation is tense: "There are a lot of people who are still in the streets with guns. They're defending the city because a lot of Gaddafi's army [is] coming here and try to attack the airport, attacking the television, attacking the radio station. We think there are some other attacks but we're still ready."
Up to 500 Britons remain in Libya. Carole Blackeway's husband Tony is stranded in a desert camp in Amal, south of Benghazi. She told the BBC she was increasingly worried about his safety: "Even though he is trying to be careful not to alarm me, his e-mails are getting more and more worrying. The army and their private armed security have left and they are stuck in their compound. A minibus with armed security arrived earlier but my husband got off it, after boarding, because he did not feel safe. I don't know if any of the other men with him continued on, but I doubt Tony would have got off by himself, as there is a real group mentality among these men. I have spoken to the Foreign Office three times today and they tell me they are trying to arrange a way of getting them out. I'll do whatever it takes to get him back."
The Libyan rebels are consolidating their hold in the east, the BBC's Kevin Connolly reports from Benghazi. They are trying to ensure basic services including food deliveries continue more or less as normal, and are setting up committees to run Benghazi in the future.
This just in from BBC Arabic's Cairo office: The Ruling Higher Military Council in Egypt has approved amendments to the constitution but delayed a debate about presidential powers until a permanent constitution is drafted.

Armed people came out of the ambulance and started shooting at the people. I can't explain the feeling how it was. I was terrified. I mean, [an] ambulance."

Today's Live Page is devoted to events in Libya but we may occasionally mention news from other parts of the Middle East. There are two developments in Egypt, BBC Arabic correspondent Mahmoud el Said reports. Youth protest leaders are meeting now to discuss their response to the army's forceful evacuation on Friday of protesters from Cairo's Tahrir Square. The army itself, which is of course running the country pending free elections, is due to review the first draft of constitutional amendments.
Another pundit quoted by AFP - a spokesman for the Geneva-based Libyan League for Human Rights who asked not to be named - explains the difference between the three countries' prospects: "Tunisia and Egypt also had dictators but with a constitution, a parliament, elections and a semblance of democracy. All this is foreign to Libya, making the challenge a bit more difficult." A bit more, indeed.
Libya is not Egypt and not Tunisia, analyst Khalil Matar has told AFP news agency. An end to Col Gaddafi's rule would create a transition period for a divided country whose institutions are weak, despite oil wealth and the enthusiasm for freedom and democracy. "Tribal alliances are more important than anything else," says the author of Lockerbie and Libya.
This just in from the UK Foreign and Commonwealth Office: British nationals who were on Cumberland have been put up in hotels in Malta. Charter flights will be provided to bring them back to the UK over the weekend, the FCO says.
Some harrowing personal stories of evacuees aboard the Cumberland are being reported by the UK Ministry of Defence. Richard Weeks, 64, said he had been robbed at knife point. The 64-year-old contracts manager from Sully near Cardiff had been working on a clean water project in Libya. "We were faced with looters rushing into the property where we were holed up and there was nothing we could do," he said. "They were armed with knives and knew they could take what they wanted, so it was better to let them get on with it. It was a very sad and terrifying situation. I've lived between Cardiff and Benghazi for 20 years and the hope is that the country can return to peace soon."
A British warship carrying evacuees from Libya also docked in Malta today. The frigate HMS Cumberland left Benghazi with more than 200 passengers, at least 60 of them British. It had to travel at a reduced speed because of the rough weather in the Mediterranean.
tweets: "Take resignations with a pinch of salt. Although they r good indications, remember these ppl supported #Gaddafi for 42yrs"

in Tripoli tweets: "Going out, Try to buy some food... It's Running out !! O.o"
What's Libyan state TV's latest take on the revolt against Col Gaddafi? BBC Monitoring picked up a commentary this morning which accuses foreign media of a "twisted campaign" to falsify information. "The truth is that the battle is among sleeper cells affiliated to al-Qaeda and its leader Bin Laden, who planted these cells long time ago," it says.
Gunfire was heard during the night in Tripoli and electricity supplies were cut, eyewitnesses say. Protesters in the second city, Benghazi, are camping out by the courthouse in solidarity with people in the capital. "I would like to say to those who live in Tripoli that we will join you soon, we will come to support you," one protester, Abdallah Alaamamy, told Reuters news agency.
