That concludes our live coverage for Monday, after another day of political turmoil and street protests in Tunisia.
The BBC's Arab affairs analyst Magdi Abdelhadi says: "Tunisians are perhaps justified in their fear of the old political class. They find it hard to believe that ministers who served Ben Ali for so long can deliver the change that Tunisians have paid for with their blood."

Interior Minister Ahmed Friaa says 78 people have died during the unrest, AFP news agency reports. The last official figure was 23 deaths, given before President Ben Ali fled.
France has been defending itself from accusations that it could have done more to help prevent the crisis. Presidential adviser Henri Guaino told France's RTL: "Imagine that France intervened in the internal affairs of a country that's a former French colony. What would people have said? And what would people have said inside Tunisia? It's not France's role to be the policeman of the Mediterranean."
Interior Minister Ahmed Friaa says the unrest has so far cost Tunisia about $2.2bn (£1.4bn), according to AFP news agency.
Natasha from Brighton, has just returned to the UK from Tunisia. She e-mails: "I was shocked to see dozens of empty seats on the BA flight from Tunis to Gatwick last night. Surely in a national state of emergency planes should be obliged to fill up! Anyway we landed in to Gatwick find to the sound of applause - thanks a lot to all the great BA staff I came across.
At his press conference, Mr Ghannouchi said: "We are committed to intensifying our efforts to re-establish calm and peace in the hearts of all Tunisians. Our priority is security, as well as political and economic reform."
has criticised foreign leaders for not intervening. "Their support to the revolution would have been appreciated, and might possibly have hastened the outcome and/or limited the bloodshed," he writes.
The post of interior minister remains with Ahmed Friaa - he has been in the post since 12 January, when his predecessor, Rafik Belhaj Kacem, was dismissed by Mr Ben Ali in one of his final attempts to pacify protesters before his resignation.
Announcing the new government, Prime Minister Mohammed Ghannouchi said: "The task of the government is to achieve a transition to democracy by reforming the laws relating to public life, and to prepare for free and fair elections under the supervision of an independent commission and in the presence of international monitors."

The exiled secular leftist leader Moncef Marzouki has dismissed the new government as a "masquerade". He told French media: "Ninety dead, four weeks of real revolution, only for it to come to this? A unity government in name only because, in reality, it is made up of members of the party of dictatorship, the RCD."
The dawn-til-dusk curfew has been in place in the capital since last Wednesday. It was shortened by three hours on Sunday after the authorities said the security situation had improved.

tweets: "I like the new government!! stop complaining people and playing the expert."
The BBC's Lyse Doucet in Tunis says of the protesters: "They want 100% - it's not enough for them that Ben Ali has been forced out of the country. They want all the president's allies to go as well. They want a new start, they want change from top to bottom."

All eyes will now be on the Tunisian public, to see whether they will accept the new leaders. One protester in Tunis, Monji Amari, told Reuters earlier: "We have had enough of this party of power. We do not want to see them any more. Together with Ben Ali they are responsible for the situation that we are in now."
The ministers of the defence and interior have also kept their jobs.
The BBC's Arab affairs analyst Magdi Abdelhadi says: "The new line up will face the enormous task of re-gaining the confidence of the people who have just overthrown their president. Given that most of the ministers are from the party of Mr Ben Ali, that will not be easy."
Tunisia's Ministry of Information has been abolished, says Mr Ghannouchi.
Reuters quotes Mr Ghannouchi as saying he is committed to freeing all political prisoners.

Ali Miaoui, who heads the French division of Tunisia's state airline, Tunisair, has praised one of the company's pilots for refusing to fly members of the former president's family into exile last week: "[The pilot] decided... not to fly... I believe he pretended he was sick or something, but in any case, he refused to fly, which later allowed members of the Trabelsi [ex-president's in-laws] family to be detained and not to travel."
Amel Gaaloul, from Tunis, tells the BBC people are very reluctant to go outdoors. "People are afraid and hesitating to go out to work. If they have made it to work, many are staying there, like a lot of my colleagues. You have to take risks by going into other neighbourhoods to find supplies, which is also pretty scary as you don't know who will stop you. We just want to see calm and peace."
The BBC's Wyre Davies in Tunis says after 23 years of living under a virtual dictatorship, Tunisians are discovering how their ex-president and his family lived in the lap of luxury. Television footage showed dozens of people wandering around the grounds of a luxurious villa, near the seaside resort of Hammamet, home to one of the former leader's privileged nephews. Some came just to look, others vented their anger by damaging opulent furnishings; the rest took their revenge by removing whatever they could lay their hands on. The swimming pool was the one thing they could not take away.
Richard Field, originally from London, lives in Tunis, and tells the BBC he has been unable to leave his home for two days: "I will have to venture outside today to find food, but I am worried. There are still soldiers, tanks and armed police on the streets outside my home and helicopters are flying overhead. I haven't got much food left. I haven't been outside since Saturday. There are no shops open nearby. I was hoping things would settle down today, with a new government being announced."
Exiled Tunisian opposition leader Moncef Marzouki tells Reuters he will be running in a presidential election to be held following the departure of Mr Ben Ali. "We need to hold credible elections," he says.
Newspapers in Morocco say the events in Tunisia will have regional repercussions. "What happened in Tunisia will weigh on the Maghreb and the Arab world," says

The US has joined the EU in saying it is ready to help Tunisia to hold free and fair elections. President Barack Obama's counter-terrorism adviser, John Brennan, who is visiting Tunisia's neighbour Algeria, said: "We applaud the courage and dignity of the Tunisian people, and we urge all parties to maintain calm and avoid violence."
An adviser to Mr Ben Ali has
been telling Le Monde newspaper
about the last few days before the president fled. "There was a ruinous atmosphere at the palace," he says. The unnamed adviser says Mr Ben Ali had responded to the news of the self-immolation by saying: "May he die."

The BBC's Wyre Davies in Tunis say the pro-democracy campaign definitely has the upper hand. "In the streets of Tunis, there were a lot of people out who have been using social networking sites to try to convince people that things are moving forward, getting back to normal. A lot of the shops aren't open and the economy isn't really working because there is a state of emergency."
Dr Hakim Darbouche, a North Africa analyst at Oxford University, told the BBC World Service the next government can only be a transitional one, but it is uncertain how long it would last. "The people we are seeing on the streets of Tunis are people who know the tricks of the regime of Ben Ali inside out. They've been at the receiving end of them for 23 years. So there's nothing that the new transition government will have up its sleeve that will go unnoticed."
The al-Arabiya TV channel is reporting gunfire in the Lafayette district of central Tunis.
The BBC's China editor, Shirong Chen, says the unrest is being watched very closely there. Hundreds of thousands of people have been commenting on internet forums, praising the Tunisian public and drawing parallels between Mohamed Bouazizi's suicide protest and the frustrations felt by many in China.

The country has very strict regulations."
In a sign of how tense things are in the capital, a group of Swedish citizens on a hunting trip in Tunisia were beaten up on Sunday night. They were travelling in taxis in the capital when they were stopped at a checkpoint and, when their guns were found, accused of being foreign mercenaries. Ove Oberg, one of the group, told reporters they had been treated "like foreign terrorists".
Mourad Teyeb is a journalist working for Al Sabbah, a newspaper owned by the ousted president's billionnaire son-in-law. He told the BBC many politicians seem reluctant to talk about what the future role of the ruling RCD party will be. "But the Tunisian people insist that the first political steps to be taken should be measures against this ruling people - very unpopular, very, very corrupt," he said.
The BBC's Wyre Davies says the intense security has made it hard to film on the streets of Tunis. He says the army does not appear to be interfering in the process of political reform, but that the motives of some of the police and security services who are still loyal to Mr Ben Ali may be more sinister.
Francis, a Tunis resident,
told the BBC he was unable to leave his home for several days
because of a curfew in the capital and is running out of basic supplies. He says vigilante gangs have been formed to protect his street. "Each evening they barricade the street and we're told to put our shutters down."
The BBC's Jon Leyne in Cairo says the man was shouting slogans about the government and unemployment. "With the close similarity to the incident that began the demonstrations in Tunisia a month ago, the Egyptian government is bound to be nervous," says our correspondent.

Many people in Tunisia are keen for their country to move away from protests and towards a new, stable leadership.
