Two people were killed in clashes between two armed groups in a Lebanese refugee camp near the Southern port city of Sidon on Monday, AFP reported.
It is unclear what sparked the fighting between members of the Jund al-Sham Islamist group and members of Palestinian president Mahmoud Abbas' Fatah movement. Among those killed were a Fatah officer.
At least six people were wounded, a Palestinian source told AFP.
Disagreements between other Islamic groups and Fatah members have escalated over the last several months.
