Six people have been killed and tens other injured in fresh violence gripping the north Lebanese city of Tripoli, amid growing fears of a spill-over from the two-year conflict in neighbouring Syria. Rocket-propelled grenade attacks struck areas across Tripoli, including Bab al-Tabbaneh, Rifa and Jabal Mohsen. Four men – Samir Hadad, Yehia Telegy, Mohamed Marie and Mohamed el-Rashid – have been named among the dead. A Lebanese soldier – named as Hassan Diab – also died, Voice of Lebanon radio station has reported. Armed forces were deployed to trouble spots, establishing security barriers in attempts to calm an already aggravated situation. Clashes continued well into early Friday. Tripoli has been witnessing deadly clashes between supporters and opponents of the Damascus regime for several years now. The majority of Bab al-Tabbaneh residents are Sunni and back the revolution against Syrian President Bashar al-Assad while Jabal Mohsen's residents are mainly Alawites from Assad's sect.
