Mutilated body NOT Margaret Hassan

LONDON -- Britain said Wednesday it believed kidnapped aid worker Margaret Hassan was likely dead, even though dental records proved a body found in Iraq wasn't hers.

The Foreign Office said dental tests were conducted on a mutilated body found in Fallujah by U.S. marines, who believed it was that of a western woman. The body was in U.S. custody, the department said.

A Foreign Office spokesman said dental records showed it wasn't Hassan's body.
