BEIRUT, Lebanon — Fighting broke out in northern Lebanon yesterday between pro- and anti-government factions leaving at least four people dead and 29 wounded, security and medical officials said.

Tensions have been on the rise for several days between government supporters in Tripoli’s Bab el-Tabaneh district and the opposition in neighboring Jabal Mohsen, according to the security officials.

Machine guns and rocket-propelled grenades were used in the clashes, which started around 4 a.m., according to the officials, who spoke on condition of anonymity because they were not allowed to speak to the press.

Three civilians were killed along with a policeman who was on his way to work when he was hit with a bullet in the head, officials said.

The latest deaths raise the number of people killed in violence since last month to 87. More than 200 have been wounded.

A military official said the fighting had eased before noon yesterday and the army was sending reinforcements.

The area witnessed heavy fighting last month when pro-government gunmen and armed men loyal to the Hezbollah-led opposition clashed in different parts of the country.

After a meeting yesterday afternoon by local leaders in Tripoli, the former prime minister, Najib Mikati, called on the Lebanese army to take control in the city.

Officials from the opposition Arab Democratic Party did not attend the meeting.

After sunset, security officials said sporadic fighting in the area resumed.

An Arab-mediated deal in May got Lebanon’s Western-backed parliament majority and the Hezbollah-led opposition to agree to form a national unity government and halt the spiraling political crisis that had escalated into violence and pushed Lebanon to the brink of a new civil war.
