Three armed people were killed and eight others injured on Sunday in clashes between the Islamic Resistance Movement (Hamas) and Fatah, the two major rival Palestinian factions, at Burj al-Shamali camp in southern Lebanon, the National News Agency reported.

The clashes took place during the funeral of a Hamas member Hamza Ibrahim Chahine, who died in Friday's explosions in the refugee camp.

Media reports stated that the explosions were caused by a fire that erupted in diesel reservoirs located near a weapons warehouse.

However, Hamas announced in a statement on Saturday that the explosions were caused by an electrical fault leading to a fire at a warehouse containing a quantity of oxygen, gas, detergents and disinfectants used to fight against COVID-19.
