Three people have reportedly been injured in a "shooting incident" in Jdeideh, a municipality located in the northern suburb of Beirut, a journalist on the ground has reported.
One of the wounded is in critical condition according to that same source.
It is unclear whether today's shooting is linked to the clashes that erupted last week.
At least ten people have died in Tripoli and two in Beirut in sporadic clashes between Sunnis hostile to the Syrian regime and Alawites who support Assad. The Alawite sect, to which the Syrian president belongs, is a branch of Shiite Islam.
Since the beginning of the Syrian uprising, sectarian tensions have flared up in Lebanon where the opposition supports those leading the uprising and the ruling coalition led by the Shiite Hezbollah supports Assad's regime.
