At least eight people were killed in fighting on Monday between Palestinian factions in a refugee camp near Lebanon’s southern city of Sidon, Lebanese and Palestinian medical sources said.

Local sources said the clashes broke out between fighters from the Brigades of Return, a group originally linked to Palestinian President Mohammad Abbas’s Fatah group, and a rival militant organization.

The leader of the Brigades of Return, Ahmed Rasheed, and two of his brothers were killed in the clashes in the Mieh Mieh camp, the sources said.
