At least four people have been killed and another twenty or so wounded during clashes in the Lebanese city of Tripoli.
Fighting erupted on Sunday between residents loyal to Syria’s President Bashar al Assad and those supporting the Syrian opposition.
At one point the Lebanese army intervened after a soldier was shot dead by a sniper.
Clashes are common between Lebanon’s Alawite community, which is the same sect as that of Syria’s president.
The fighting underlines how tensions in Syria are threatening to spill over to its neighbours as the continued unrest there keeps claiming victims.
Renewed shelling was reported in Homs and Syrian troops are said to have shot dead seven civilians in a Sunni Muslim village west of the city of Hama.
Four women were among those killed – Opposition activists said the village is one of dozens torched since Assad’s forces seized control of the region.
