The Taliban has claimed responsibility for an attack on a British military base in Afghanistan that killed two U.S. Marines.

A spokesman for the militant group said Saturday the attack was in response to a film that insults the Prophet Muhammad, and because Britain's Prince Harry is serving at the base.

Military officials say insurgents used mortars and rockets overnight against Camp Bastion in Helmand Province. Several troops were wounded in the attack.

Officials say Prince Harry, who is third in line to the British throne, was never in any danger. He is deployed there as a helicopter pilot. The Taliban has vowed to kill him.
