ISTANBUL - An Islamic State militant was killed after detonating explosives strapped to their body when Turkish police raided a militant cell in a house in the southeastern city of Gaziantep on Thursday, the Dogan news agency reported. Turkish police on Monday issued a nationwide warning about possible Islamic State (IS) attacks on Thursday, a national holiday, after the army stepped up attacks on the militants in Syria.
