SANAA (AFP) - Four Yemeni policemen were among seven people killed in clashes between security forces and suspected Al-Qaeda militants, a security official told AFP on Thursday. Two armed men wanted by the authorities and a civilian were among those killed in the incident which took place on Wednesday in the southern Yemeni town of Joaar, the official told AFP on condition of anonymity. "Four members of the security forces, two armed men sought by the justice department, and a civilian were killed in clashes Wednesday morning between police forces and a group of Al-Qaeda sympathisers," he said. The security forces were chasing Samy Dyan, thought to be one of the fiercest fighters of Al-Qaeda in Yemen, and clashed with armed men who were hiding in a house in Joaar, the official said. The suspects set a police car ablaze and fled to a nearby mountainous region as police reinforcements arrived on the scene, the official added. Yemen, the ancestral homeland of Al-Qaeda chief Osama bin Laden, has seen a series of assaults on security forces and oil installations in recent months claimed by groups linked to Al-Qaeda.
