British Prime Minister Gordon Brown says a body handed over to officials in Iraq is that of missing security contractor Alec MacLachlan.

Brown said Thursday tests on the remains received by British officials Wednesday had confirmed MacLachlan's identity.

He was one of five Britons abducted by Shiite militants in a raid on Iraq's Finance Ministry in 2007.

The bodies of two other men were returned to Britain in June. Brown called on the hostage-takers to release IT consultant Peter Moore and to confirm the fate of Alan McMenemy, who is feared dead.

Moore, an IT consultant, was being protected by the security contractors when all five men were seized by militants disguised as Iraqi policemen. British officials believe Moore is still alive.
