At least seven people were killed and 10 others injured during clashes that broke out Monday at the Palestinian refugee camp of Mieh Mieh in Lebanon's southern port city of Sidon.
A security source confirmed to Xinhua the toll, pointing out that the clashes started as an individual dispute 10 days ago.
The source said that armed clashes erupted between supporters of "AnsarUllah" group and others of Fatah movement.
The military commander of Ain El-Heloue, the largest Palestinian refugee camp in Lebanon, said various factions at the camp tried to ease the tensions caused by the individual dispute, but they failed.
He added that the Palestinian factions, in coordination with the army, are working on resolving the dispute. The clash saw the use of medium and heavy machine-guns and rocket-propelled grenades.
The army has since taken strict security measures around the camp in order to prevent escalation.
