Peter Kassig’s family in video appeal

THE parents of US hostage Peter Kassig have appealed in a video to Islamic State militants to “show mercy” and release him.

Calling their son by the name he now uses, Abdul-Rahman, Ed and Paula Kassig say they are proud of their son and his aid work.

It follows the release of an IS video on Friday, which showed the beheading of British aid worker Alan Henning. That video ended with a threat to kill 26-year-old Mr Kassig.

It was the fourth such video released by the group calling itself Islamic State.

Previous victims were American reporter James Foley, American-Israeli journalist Steven Sotloff and British aid worker David Haines.

In the video Mr and Mrs Kassig appear on a sofa. Paula Krassig is wearing a headscarf and clutching a photo of their son.
