Scores of people were killed when a suicide bomber drove a car into a crowded area near an Iraqi police station in Baquba.
There were also further causalities south of Baghdad where Iraqi soldiers were fighting insurgents.
It has been a month since sovereignty was handed over to the Iraqis.
More than 160 Iraqis have been killed since the interim government took power on 28 June.
What does this mean for Iraq's interim government? Are they doing enough? What more do you think they could do to boost security and so bring peace to Iraq? Do they have the resources to do so?

The following comments reflect the balance of opinion we have received so far:
Invading Iraq was worse then a crime, it was a blunder. The US and the UK had the courage to destroy the Iraqi infrastructure but now have no backbone to take the responsibility.
Yann Chambrier, Hong Kong
Bush and Blair opened Pandora's Box. Now they have to live with it.
Jan P, Belgium
The answer is simple - withdraw the Western troops and replace them with an Islamic peacekeeping force. The Iraqis will soon de-escalate the violence when it is their co-religionists keeping the peace in their country.

Bringing peace depends on bringing economic and social welfare to Iraq.
Olcay Hartoka, Istanbul, Turkey
The horror we see occurring in Iraq today is simply a case of the chickens coming home to roost. Nothing good can come out of something that was so flawed to begin with.
Yaakov Sullivan, New York, NY
It is clear that there is a civil war at hand. What government in it infancy has been established without a civil war? The violence is horrific. War is always violent, and horrific. We make war, and we must make peace. Is one possible without the other?
Georgine, Vancouver, WA, USA
It is sad to see such stories in the news. The only way to resolve this is redraw the borders and give the Kurds, Sunni and Shia each their own country. This clinging to the idea of multiculturalism is just going to cost to much blood.
160 dead? that is a high figure. But if there was an official figure for the victims of Saddam's tyranny in July 2002, I am convinced it would be much higher, but no one saw the victims on TV, so no one bothered.
Marcin Wilk, Freiburg, Germany
There can't be any peace without the support of the local people. The coalition forces should do all they can to win the heart of common Iraqis because only Iraqis could help the force to root out insurgents

Since I was a child I've listened to my grandparents saying something like this: "Everything that starts wrong ends up wrongż" Let's be honest, what Mr Bush and Mr Blair has been done is a great and huge mistake... nonsense... madness...
Marano Junior, Gennaro, Sao Paulo, Brazil
Compare Iraq today to post-WWII Germany. Quit whining - just read history.
Mark C Allman, Boston, MA, USA
It's time we stopped buying all this nonsense about insurgent terrorists and realise that we are on the edge of what looks like a civil war. The interim government has little moral authority or domestic support, the fall of Saddam has created a power vacuum and there are groups who believe that they can fill that gap. The only way forward is to find public support, and that probably means shedding a few of the obvious US appointments to the interim government and introducing religious leaders and others are more acceptable to the Iraqi people.
Mike, London, UK
Robert Fisk reports in today's Independent how he visited a mortuary and was told that over 500 Iraqis had died in the last three weeks in Baghdad alone. A quick look at news reports from many diverse sources shows that the level of violence and death amongst Iraqi civilians is far higher than most TV bulletins and newspapers are currently reporting. It would appear that most international news organisations only make a big issue of an event when it involves dozens of Iraqis being killed at once. Whilst reporting events like today's is understandable from a shock factor point of view, it should not mean that the deaths of 300 other Iraqis is not given the same level of coverage.
Andrew Hirst, Leeds, UK
Until and unless the Iraqis unite against the terrorists, peace cannot be achieved. The animosity and mistrust amongst Sunni and Shia leadership is helping the terrorists to exploit the situation to their advantage. As long as the coalition forces remain in Iraq, the people of Iraq will consider them as invaders and occupiers of their land; and the interim government as the facilitators of occupation. The sight of an American soldier is a reminder of invasion of their country more than the removal of Saddam Hussein. The interim government should encourage participation of Sunnis and Shias in the running of their country at local level to build their country.
Saqib Khan, London, UK
The American British forces have plenty of security for their people. They have removed the Iraqi army and destroyed Iraq's infrastructure. They had very little thought for security for the people of Iraq. It is time humanity started to put pressure on these vast security well armed forces to do the job properly and provide security until Iraq is able to rebuild its infrastructure and army.
Ahmad Hmoud, Jordan, Amman
This just shows that the insurgents are just against a new Iraq rather than the coalition, they obviously just have a lust for killing innocent people. Absolutely disgusting, how can this situation be solved? Iraq is already a sovereign nation!
Dan, Newbury, UK
I want George Bush and Blair to take full responsibility for these acts. They are the occupying force and law and order is their responsibility. Would Mr Bush sit cosily at his ranch if this act was committed in the US?
Most know that the interim government was appointed and is controlled by the US government. If we want to restore peace to Iraq we must gain their trust. And the biggest way is to admit to the mistakes. All US and UK companies withdraw from Iraq. The US and UK should not be allowed to obtain or gain any profits of any of Iraq's resources for years to come. If this is about freedom for the Iraqis then let's prove it to them.
The carnage going-on in Iraq today is a by-product of US sponsoring of terrorism against perceived enemies in the 80s and 90s. Having falling out with Saddam, US and its allies had to invade Iraq on trumped charges without the approval of the UN. Now, without a powerful and legitimate government to wield the Shia, Sunni and Turks together, the terrorists are now having a field day. Shame on Bush and Blair and their fast declining rabid supporters.
Joel Ikechukwu Ojiakor, Lagos, Nigeria
These people who carry out such attacks are not people who have a greater interest in Iraq or the Muslim faith; they are weak minded individuals that hide behind a facade. One that pretends to uphold and honours both but they are a mere cloak for self interest and preservation.
Any nation, when it is just freed from the clutches of a dictator or another country, goes through a transitional phase. What Iraq is undergoing is perfectly natural. If we look back in history, take India for example. The days after it was granted independence were the most violent days, both for India and Pakistan. But haven't the two nations progressed?
Shweta Bhat, Bangalore, India
The violent in Iraq is exactly what the Americans and the British wanted. Now they have the reason to stay and occupy Iraq in the name of bringing peace (which will never come as long as they are there). The main reason for going to war has faded so fast and nobody talks about it anymore. Right now, the only solution to peace and security in Iraq is for the foreign forces to withdraw and leave, there is no need for them there, if there is no peace, then there is nothing to keep, and then peace can not be brought by that kind of destruction. Please leave.
Mike Aziz, Vancouver, Canada
160 dead this month, how many will die in August? This is a shambles and I'm not sure who can put it right. The Iraqis obviously can't and the International-US forces don't appear to be doing any good. So with hindsight been a precise science, perhaps we should have just left them to it in the first place and not gone looking for WMD etc etc... The loss of life is now diabolical!
Mal Wilkinson, Hull, UK
There is only one way out of Iraq: break up Iraq into three nations you will save many many lives of both the Iraqis and the foreign troops.
Saman, Birmingham, UK
If 100,000 hardened criminals are let free from prison (by the coalition), who can be surprised if there is violence on the streets? Obviously, the police will be the targets because they led them to jail in the first place.
Geoff, Cambridge, UK
Freedom is not free... The Iraqi people have been suppressed for years. If they really want freedom they will have to sacrifice and work for it. No one else can give them freedom but themselves.
Rocky, Vermont, USA
It's the price the Iraqi people and coalition forces will have to pay for being dragged into a war by greedy rich, and incompetent men in Washington. I like Tony Blair but I am disappointed, that he allowed Washington to drag him down the tubes with them.
Tony, New York
The complete mess which Iraq is in at present (thanks to the war) has created an air of despair and apathy, which I believe is contributing to the increasing numbers of bombings. I do not believe that the Iraqi forces are sufficiently equipped to tackle the threat from terrorist groups and suicide bombers (160 dead since handover date). I believe that peace is a long way away and I cannot comment on how it may be achieved. The sad truth is that the war on Iraq has lead to a clear increase in terrorist acts, and now the Iraqis are left ill-equipped to deal with this abominable situation.
Adam, Halifax, UK
The insurrection in Iraq proves that there is, if not active support, at least silent approval of the fight against US troops and the Iraqis who support them. The interim government has a very thin line to walk on. If it adopts US policy of bombing suspects it will look just like a puppet regime, if it vetoes US decisions on use of military power it runs the risk of loosing all its resources. I suspect the US will find very difficult to reduce the use of military power and soon the interim government will have no room to manoeuvre. Then it will in the difficult point of choosing either to infuriate the US or the Iraqis.
