A series of blasts in Baghdad killed 95 people and wounded 536 in Iraq's bloodiest day this year, prompting a rare admission of culpability from Iraqi security forces struggling to cope without US help.
At least six blasts struck near government ministries and other targets at the heart of Iraq's Shia-led administration, weeks after US combat troops withdrew from urban centres in June, thrusting Iraq's security forces into the lead role.
"We must face the facts. We must admit our mistakes, just as we celebrate our victories," Defence Ministry spokesman Major General Mohammed al-Askari told a group of US and Iraqi military officials today through an interpreter.
His comments echoed earlier remarks by Baghdad's security spokesman, Major General Qassim al-Moussawi.
"This operation shows negligence, and is considered a security breach for which Iraqi forces must take most of the blame," Mr Moussawi told Iraqiya state television.
The sectarian war that savaged Iraq after the 2003 US invasion has abated and Iraq celebrated the restoration of its sovereignty in June when US troops withdrew from cities.
The government this month ordered most blast walls in Baghdad to be removed within 40 days, a sign of faith in its troops and police before a national election in January. But today's coordinated attacks on heavily guarded targets shattered a growing sense of optimism about Iraq's stability.
In one blast, a massive truck bomb close to a checkpoint for the heavily fortified Green Zone blew out the windows of the foreign ministry. Dozens were mown down in a blizzard of glass.
The explosion was powerful enough to blow in some windows of Iraq's parliament building in the Green Zone.
The attacks could undermine confidence in Prime Minister Nuri al-Maliki before the parliamentary election, and could also deter foreign investors, especially oil companies, which might have started to think of Iraq as a place to put their money.
Mr Maliki called an emergency meeting to reevaluate the defence of Baghdad. He said in a statement that the attacks were aimed at "raising doubts about our armed forces, which have proven themselves very capable of confronting terrorists".
No group claimed responsibility, but Moussawi said two members of al-Qaeda were arrested when another car bomb was intercepted. Iraqi television later showed a truck loaded with water tanks stuffed with explosives that had been disarmed.
The second truck bomb in Baghdad's Waziriya district close to the finance ministry killed at least 28 people and caused huge destruction. Part of a raised highway nearby collapsed.
The Baghdad provincial government building came under mortar attack, police said, as did the Salhiya district in central Baghdad, home to army bases and a television station.
At least one suspected mortar round landed near the United Nations compound in the Green Zone, startling UN workers marking the sixth anniversary of the destruction of their previous Baghdad headquarters by a truck bomb which killed envoy Sergio Vieira de Mello and other staff, UN guards said.
The US military said it had no reports of mortar fire. In Bayaa, in southern Baghdad, a blast killed two people.
