Palestinian vs Palestinian

Reuters reports:

Three Palestinians were killed in fighting between rival factions at a refugee camp in south Lebanon on Monday, security sources said.

The fighting began when gunmen shot dead a member of the Islamist Jund al-Sham militant group in Ain al-Hilweh camp, 40 km (25 miles) south of the capital Beirut.

The killing triggered fierce exchanges of gunfire and grenades between the militants and Fatah gunmen in which a second Jund al-Sham member was killed.

Few hours after the fighting stopped, the father of a senior Fatah official was shot dead by unknown attackers.
