In Lebanon, at least five people were killed Sunday during clashes between rival groups in one of the largest Palestinian refugee camps near the city of Sidon. The fighting broke out after an unknown gunman tried to assassinate an Islamist militant leader, killing a companion instead. In response, militants killed a military general and three other members of the Fatah group, which is part of the Palestinian Authority. At least seven people were also wounded in the violence, including at least two children. Palestinian factions in the camp have for years cracked down on militant Islamist groups. The overcrowded Ein el-Hilweh camp houses some 55,000 Palestinians.
