Video posted on a social networking website by Taliban sources seems to show the aftermath of an attack by the Taliban on Camp Bastion, in Afghanistan.

Two US marines were killed and several more were wounded.

The Taliban now say they were targeting Prince Harry who is in the Helmand Province for his second tour of duty.

At the time of the attack he was two kilometres away with fellow Apache helicopters pilots.

The amateur footage, which cannot be independently verified, shows dark smoke rising over the base compound.
