The Yarmouk Palestinian refugee camp near Damascus that has been overrun by Islamic State fighters is “the deepest circle of hell” in Syria’s four-year horror, the UN secretary-general says.
Ban Ki-moon told reporters that “a refugee camp is beginning to resemble a death camp” for its estimated 18,000 residents.
He warns that the armed fighters inside the camp and Syrian government forces outside it are a double-edged sword for the thousands trapped.
“We simply cannot stand by and watch a massacre unfold,” Mr Ban says.
IS fighters overran much of the Yarmouk camp last week.
The secretary-general is demanding an end to the fighting, access for humanitarian aid and safe passage for people who wish to flee.
