Iraq's new prime minister says his government co-operated in a US air strike on the town of Falluja, which killed at least 10 people.

In an unprecedented statement, Iyad Allawi said his interim government had provided intelligence for the attack.

A US military spokesman said the target was a house suspected of being used by supporters of an al-Qaeda leader, Abu Musab al-Zarqawi.

This was the first US strike against Falluja since the handover of power. The US airforce has attacked the town five times in the past two weeks.
