CAIRO/GAZA: Four people were killed and others were injured in a shooting on Sunday in the Palestinian camp of Burj al-Shemali in Lebanon, two officials of the Palestinian Islamist group Hamas told Reuters, and they blamed rival movement Fatah for the bloodshed.

The shootings took place during the funeral of a Hamas supporter who was killed in an explosion on Friday night in the camp in the southern Lebanese port city of Tyre. “Fatah gunmen deliberately opened fire against people taking part in the funeral march,” one Hamas official said, asking not to be named.

There was no immediate response from the office of the Palestinian ambassador in Lebanon to a Reuters request for comment about the Hamas allegation. Fatah controls the Palestinian Authority that exercises limited self-rule in the Israeli-occupied West Bank. Palestinian Authority officials in the West Bank, contacted for comment by Reuters, said they were checking the reports.

Earlier on Sunday, Lebanese state media said two people were killed and seven were injured in a dispute that erupted in the Burj al-Shemali camp. Hamas said in a statement on Saturday that the blast on Friday night was caused by an electrical fault in a warehouse containing oxygen and gas cylinders for coronavirus patients, as well as detergents and disinfectants.

A number of armed Palestinian factions, including Hamas and the Fatah movement, hold effective control over roughly a dozen Palestinian camps in the country, which Lebanese authorities by custom do not enter.
