Two people were killed in a Palestinian refugee camp in Leba**n in renewed overnight clashes between the mainstream Palestinian faction Fatah and hardline Islamists, security sources said. The two sides exchanged heavy gunfire in Ain al-Hilweh refugee camp in southern Leba**n, which has regularly seen factional disputes spiral into deadly violence. The two men killed were from Fatah, the sources said, and the violence displaced a large number of the camp's inhabitants.
