A suicide bomber killed 40 people and wounded 34 others in the reception area of a Baghdad college today as insurgents defied efforts by US and Iraqi security forces to stabilise the capital.
Police said the bomber was wearing a vest packed with explosives and had tried to enter the grounds of Baghdad's Economy and Administration College when guards stopped him. He then blew himself up, police said.
Insurgents have regularly attacked universities in Baghdad. The attack was among a string of car bombings and rocket strikes across the city today.

Prime Minister Nuri al-Maliki expressed optimism yesterday about the 10-day-old security plan and said US and Iraqi forces had killed about 400 suspected militants since it began.
US forces have set up joint security outposts with Iraqi forces around the city and the crackdown does appear to have reduced the number of bodies found tortured and shot in the city, apparent victims of death squads.
A typical daily body count had been around 40 or 50 a day in recent months but since the start of the plan it has been between five and 20. However, US commanders say it will take months to judge the success of the offensive.

The lorry bomb in Habaniya, in the restive western province of Anbar, was unusual in targeting a Sunni Muslim mosque.
Some Sunni tribal leaders in Anbar are leading a campaign to fight al Qaeda, which is deeply entrenched in the province, and the attack signals an escalation of the power struggle in an area where US troop reinforcements are soon to be deployed.
US President George W. Bush is sending 21,500 extra troops to Iraq to help with the clampdown in Baghdad. Most are heading for the capital although 4,000 will be sent to Anbar, the most dangerous province in Iraq for American forces.
