Gunfire was heard Sunday at the Ain el-Hilweh Palestinian refugee camp during the funeral of Fatah Movement official Suleiman Abu al-Nimr, who was killed in a blast Saturday, state-run National News Agency reported.
It earlier reported that cautious calm was engulfing the camp after a hand grenade exploded overnight on the camp's al-Fawqani street without causing casualties.
A few volleys of machinegun fire were also heard in the morning amid a total closure of shops, NNA said.
