An Al Qaeda-linked group in Iraq has killed British hostage Kenneth Bigley, according to an Islamic web site.

Bigley was abducted on September 16 with two Americans, Eugene Armstrong and Jack Hensley, who have since been beheaded.

The Tawhid and Jihad group of Jordanian terror mastermind Abu Musab al-Zarqawi abducted them from their home in Baghdad.

The web site where the posting appeared has often carried messages from Zarqawi's followers, including videos showing Hensley and Armstrong being killed.
