There was cautious calm in the southern Palestinian refugee camp of Ain el-Hilweh on Sunday morning, hours after tension that was caused by grenade attacks.
The state-run National News Agency said eight grenades were tossed in the camp's different neighborhoods. Gunmen also opened fire without causing casualties.
The joint security forces worked on opening an investigation to hold accountable the parties responsible for the tension, said the agency.
It added that Palestinian officials expressed fear over the return of gunbattles to the camp that lies near the city of Sidon.
Several people were killed last month when Fatah Movement gunmen and Islamists clashed at the camp.
Ain el-Hilweh is an impoverished, overcrowded camp home to some 61,000 Palestinians, including 6,000 who fled the war in Syria.
