Clashes intensified late Sunday in the Lebanese northern port city of Tripoli, killing at least six people and wounding more than 30 others, Lebanese police and hospital sources said, dpa reported.
"The situation has largely deteriorated in Tripoli as dozens of rocket-propelled grenades hit the frontiers between the rival neighborhoods of Bab al Tabbaneh and Jabal Mohsen," the state-run National News Agency reported.
The violence started Friday when an Alawite resident of Jabal Mohsen, which is home to many supporters of the Syrian regime, was shot in Bab al-Tabbaneh, a mainly Sunni district where many people back rebels fighting to oust President Bashar al-Assad.
After Sunday's clashes, the death toll rose to 10 people killed and fifty others wounded since the fighting erupted on Saturday, hospital sources said.
A Lebanese security source said the army was responding to the sources of fire in a bid to contain the situation.
Northern Lebanon's Sunni-Muslim Sheikh, Malek al Shaar, called on the Lebanese authorities to intervene and exert pressure to end these clashes "immediately."
The 32-month conflict in neighbouring Syria has repeatedly spilled over into Lebanon, where al-Assad's backers and opponents have occasionally engaged in deadly fighting.
