ALEPPO, Syria — On the way to Sheikh Najjar Industrial City from Aleppo, we stopped for coffee at a roadside kiosk. Its owner, Mohammed Sabri, a Palestinian refugee, had posted on the walls of his modest business photos of Palestinians killed in clashes. Prominently displayed was one of his son Khaled, who was killed in Nairab refugee camp by armed opposition groups. Seeing the photographs of Palestinian casualties made me wonder about the standing of the Palestinians in the Syrian civil war. Our Palestinian driver said that for the answer to my question, I had to visit the Nairab Palestinian refugee camp. We decided to stop there on our way back from Najjar.

It is a typical Palestinian refugee camp: small tenements surrounded by high walls, haphazardly built, multistory buildings, animated streets and the inevitable Gaza Martyrs Cemetery. The camp, established in 1956, normally has a population of 27,000. But with more people seeking refuge from the war, it now houses about 50,000 people.

Palestinians in Syria are split over the civil war. Those supporting Hamas joined ranks with the opposition, and those affiliated with Fatah and the Popular Front for the Liberation of Palestine (PFLP) back the regime.

In the first four years of the war, 209 Palestinians from Nairab out of 4,000 overall in Syria were killed. I was taken to a tea garden that now serves as the headquarters of the Jerusalem Brigade, which defends Nairab. Its commander, Adnan al Sayyid, is the son of a family expelled from Zefat by Israel. A Fatah member, Sayyid explained that the tea garden had actually been his restaurant, which he turned into a headquarters.
