A leading Irish republican is set to appear in court charged with the murders of two British soldiers in Northern Ireland. Colin Duffy is accused of killing Patrick Azimkar and Mark Quinsey at Massereene army barracks in Antrim earlier this month. The two soldiers were gunned down outside the base while collecting pizza.Duffy, who was freed on Thursday after a legal challenge to his detention, was quickly rearrested. He also faces five counts of attempted murder and possession of a firearm and ammunition. The Real IRA, a republican splinter group claimed to have carried out the murders two days before another breakaway group said it killed a policeman. The attacks shattered the relative calm brought about by the Good Friday Agreement which ended years of violence in Northern Ireland.
