Old tensions between Sunni Muslims and Alawites in Lebanon's second city Tripoli have flared up due to the continuing Syrian conflict, which has seen Bashar al-Assad's Alawite minority clash with the mainly Sunni opposition.
The Lebanese government is attempting to quell the violence between the Sunni district of Bab al-Tabbaneh and the neighboring Alawite district Jebel Mohsen.
The BBC reported that Lebanese Prime Minister Najib Mikati, a Sunni, urged citizens "not to allow anyone to transform you into ammunition for someone else's war."
Referring to the Syrian crisis, he said: "We have repeatedly warned against being drawn into this blaze that has spread around Lebanon."
Over 100 people have been wounded since violence erupted Monday night. According to Reuters, rocket-fuelled grenades shook the city in the small hours of Wednesday morning.
