One of the main Algerian Islamist terror groups on Wednesday denied any responsibility for the slaying of 14 people at a roadblock south of the capital last week. The al-Qaeda aligned Salafite Group for Preaching and Combat (GSPC) posted its disclaimer to an Islamic website. GSPC and the other principal militant group, the Armed Islamic Group (GIA) are the main police suspects for the massacre. Troops are involved in a major manhunt for the attackers, authorities said.On 7 April, Algerian Islamic militants stopped cars at a bogus roadblock near the town of Larba, about 30 kilometres south of Algiers, forcing the passengers out and shooting them dead, before burning their bodies. A truck driver escaped and told the authorities the attackers numbered about 10 men. The only other survivor was an old woman who is recovering in hospital. Police and security experts said hard-line members of GSPC, which has been fighting an Islamic holy war of 'jihad' for 13 years, have recently stepped up their attacks in a bid to scupper a general amnesty expected to be offered this year to rebels and members of the armed forces.
