Baghdad: Four people were killed and eight wounded when a suicide bomber detonated an explosives-filled vest at a mosque in Fallujah on Friday, the Interior Ministry said.

The bombing took place around mid-day at the entrance of Al Rahman mosque in the centre of the town in Anbar province, it said, adding that a police major was among the wounded.

The US military said on Friday the Iraqi Army discovered 15 bodies in a mass grave near the town of Kazim Al Isrhail.

All of the victims were male, and one was of an Iraqi soldier, who was identified by his Iraqi Army ID card. The bodies are reportedly at least 10 days old, and some of them were found with gun shot wounds to the head. That followed the unearthing of a mass grave in violent Diyala province.

Iraqi authorities said 15 bodies were found there as well, though the US military put the figure at nine - six men and three women.

Also, a US soldier assigned to the Multi National Division - Baghdad has died from a non-combat related illness, the military said yesterday. The soldier died on Thursday.

At least 3,970 members of the US army have died since the beginning of the Iraq war in March 2003, according to an Associated Press count. The figure includes eight military civilians.
