Fourteen Palestinian refugees were reported killed and another 43 injured on Monday, a report from the Palestinian government's WAFA news said.
The victims were part of a massive group in Al-Yarmok, an unofficial Palestinian refugee camp in the Syrian capital of Damascus, mourning the death of between 10-23 Palestinians by Israeli fire on the Golan Heights ceasefire line the day before.
Angered over the failure of camp leaders to organize demonstrations marking the Naksa, the anniversary of Israel's occupation of the West Bank, Gaza, and Golan Heights, an estimated 100,000 mourners were said to have attacked the headquarters of the Popular Front for the Liberation of Palestine - General Command.
