A bomb exploded early on Monday at the southern Palestinian refugee camp of Ain el-Hilweh, breaching a ceasefire agreement reached a day earlier, as clashes resumed between the secular Fatah Movement and members of two small Islamist groups.
The intersection at the vegetable market-al-Tiri in al-Fawqani street witnessed sniper shooting and bomb explosions, added the agency.
In the evening, TV networks said a new ceasefire agreement was reached after a meeting at Usbat al-Ansar official Sheikh Abu Tarek al-Saadi.
NNA has reported in the afternoon that Fatah fighters were advancing against the Islamist militants in the al-Tiri neighborhood, the stronghold of the Islamist groups.
Two Islamist militants were killed and another was wounded in the clashes, the agency added, reporting an injury toll of eight on Monday.
A ceasefire had been reached Sunday after a night of violent clashes that left two people dead and around seven wounded, media reports said.
