Islamic extremists threaten to kill three hostages

Muslim militants have threatened to kill three more hostages in their jungle base in the southern Philippines more than a week after beheading a Canadian man when their multi-million dollar ransom demands were not met.

In a video circulated on Tuesday by the SITE Intelligence Group, which monitors jihadi websites, the captives from Canada, Norway and the Philippines pleaded for the Canadian and Philippine governments to heed the Abu Sayyaf militants' demand.

Six heavily armed Abu Sayyaf fighters stood behind the hostages, who were made to sit in a clearing and spoke briefly before a camera. A black flag hang in the backdrop of banana trees and lush foliage.
