Algerian Islamic militants killed two civilians and two guards in separate attacks west of the capital Algiers, newspapers reported on Monday. A unit of 25 rebels of the Salafist Group for Preaching and Combat (GSPC) shot dead two family members on Saturday night in a village in Ain Defla province, 120 km (75 miles) west of Algiers, reported newspaper Liberte citing unnamed sources. Hours earlier, two communal guards were killed and four others wounded in the same province, newspaper El Khabar said. It was not immediately clear whether the al Qaeda-aligned GSPC was behind this attack as well.About 40 civilians and security forces members have been killed over the past four weeks as rebels step up a campaign to disrupt an amnesty planned for militants and security forces later this year aimed at ending Algeria's long-running conflict. No group claimed responsibility for the latest attacks and authorities were not immediately available for comment.
