UK leader: British hostage's killers must be found

CAIRO (AP) — The Islamic State extremists who have beheaded another Western hostage are deaf to reason and must be destroyed, British Prime Minister David Cameron said Saturday as Muslims worldwide were urged to pray for the victim on one of Islam’s holiest days.

Cameron, speaking after a security briefing at his rural retreat Chequers, said Friday’s slaying of 47-year-old English aid worker Alan Henning demonstrated that Islamic State militants were committed to inflicting horror for horror’s sake.
