Thousands of mourners gathered in south Lebanon on Monday for the funeral of a Palestinian military general with the Fatah group, whose killing in a refugee camp in Lebanon fueled fierce sectarian street battles that have killed at least nine people.

Three days of clashes between Palestinian factions at the Ein el-Hilweh refugee camp have pitted members of President Mahmoud Abbas’ Fatah party against Islamist groups accused of gunning down the general, Abu Ashraf al Armoushi, on Sunday.
