The horrors just keep getting worse for Palestinians in the Damascus refugee camp in Yarmuk, where, after enduring two years of famine and siege, an eyewitness says he saw ISIS terrorists beheading civilians and playing soccer with their heads.
That's when Abdel Fatah fled for his life.
"I saw severed heads," he said. "They killed children in front of their parents. We were terrorized. We had heard of their cruelty from the television, but when we saw it ourselves ... I can tell you, their reputation is well-deserved.
Fatah found temporary refugee with his wife and seven children at the Zeinab al-Haliyeh school in Tadamun, a southeastern district of the Syrian capital held by the army.
The school is currently home to 98 displaced people, among them 40 children, who have been put up in three classrooms.
Anwar Abdel Hadi, a Palestine Liberation Organization official in Damascus, said 500 families, or about 2,500 people, fled Yarmuk before ISIS fighters attacked the camp last week.
The camp has been encircled for more than a year, but is now reported to be almost completely under the control of ISIS and al-Qaida's local affiliate, Al-Nusra Front.
According to Britain-based monitor the Syrian Observatory for Human Rights, nearly 200 people had died in Yarmuk from malnutrition and lack of medicines before last week's bloody assault.
"In Palestine Street, I saw two members of Daesh (the Arabic name for ISIS) playing with a severed head as if it was a football," said 16-year-old Amjad Yaaqub.
Wearing a baseball cap sideways, rapper-style, the youth has a swollen eye and chin.
"Daesh came to my home looking for my brother who's in the Palestinian Popular Committees. They beat me until I passed out and left me for dead," he said.
"I left without bringing any belongings. My husband wasn't able to join me. I walked out hugging the walls so snipers couldn't see me," said 19-year-old Nadia, nursing her two-month-old baby.
