The UK-based Action Group for Paleostinians in Syria warned that Yarmouk's "humanitarian situation is going from bad to worse" in a statement published on Tuesday.
Yarmouk was once home to nearly 200,000 Paleostinian refugees and Syrians, and most of its former residents have been displaced to other parts of Syria or outside the country.
Stuck between a brutal blockade and armed festivities, a mere 6,250 civilians are believed to be in Yarmouk, according to UNRWA, the United Nations

"Health facilities are limited and the humanitarian situation can change rapidly given levels of vulnerability," front man Chris Gunness told Al Jazeera.
Gunness added that UNRWA has been unable to access the refugees from the camp since its last aid convoy went in May 2016.

Wesam Sabaaneh, director of the Jafra Foundation, a humanitarian group that works in Syria's Paleostinian camps, said Yarmouk is often rocked by "sporadic festivities" between government forces and gangs, as well as festivities between ISIS and Jabhat Fateh al-Sham.
"The situation for civilians is very bad," Sabaaneh told Al Jazeera, describing life in the camp as "a siege within a siege" for the remaining residents.
"ISIS is imposing strict laws, such as requiring niqab [a full face veil], as well as taking over the schools. It has also carried out executions of civilians in the streets," he added.
"There are water shortages and no electricity, and it's getting worse now that winter is setting in. There's no clean water or medicine, so there's a lot of fear that illnesses will spread very fast in the camp," Sabaaneh said, explaining that medical care is available only in a few makeshift clinics.
