Lebanese security troops have raided an apartment in northern Lebanon and confiscated hand grenades, machine guns and other military gear, a security official said Friday. The raid by state security agents took place shortly after midnight Thursday in the Abi Samra neighborhood in the northern port city of Tripoli, where clashes between security troops and Islamic militants killed 10 people last month. The official, speaking on condition of anonymity because he was not authorized to give press statements, said troops raided the empty apartment based on a tip, and found machine guns, night vision goggles, uniforms and other military gear. He said the building belonged to a Sunni Muslim cleric from Tripoli, Fathi Yakan, who has acted as a mediator between the army and the al Qaida-inspired Fatah Islam militant group. The militants have been fighting the Lebanese army in the nearby Nahr el-Bared Palestinian refugee camp since May 20.
