Clashes broke out late Wednesday between mainstream Fatah fighters and others from Jund al-Sham at the Ain el-Hilweh Palestinian refugee camp near the southern port city of Sidon, the state-run National News Agency said.

It said the clash around 9:30 pm erupted when Jund al-Sham fighters raided a Fatah position at the camp's upper entrance.

But fighting quickly died down following the intervention of the political factions in Sidon, NNA reported.

It said tension, however, prevailed in the camp.
