In a message to international institutions, Yarmouk residents said many people, including children, are dying on a daily basis since the camp came under siege as a result of clashes between foreign-backed militants and members of the Palestinian revolutionary committees.
They said medical equipment, including oxygen supplies, are not allowed into the camp and that a number of patients have suffocated to death as a result.
The refugees also complained of lack of fuel and flour in the densely-populated camp. They have called for international humanitarian aids, including food and medicine, to save them from gradual death.
Some observers are likening Yarmouk to Gaza, and say while Palestinians there are being killed by Israel, those in Yarmouk are falling victim to attacks by al-Qaeda.
According to sources inside the camp, there are also deadly clashes between members of the terrorist Free Syrian Army and the al-Qaeda-linked al-Nusra Front inside Yarmouk and that armed men affiliated to the al-Nusra Front have executed a number of Palestinian civilians in the refugee camp.
Yarmouk and the districts surrounding it have borne the brunt of the turmoil in Syria over the past months. In September, at least 20 people were killed after mortar shells fired by militants landed in the Palestinian refugee camp.
Syria has been experiencing unrest since March 2011. Many people, including large numbers of army and security personnel, have been killed in the turmoil.
The Syrian government says the chaos is being orchestrated from outside the country, and there are reports that a very large number of the militants operating in the country are foreign nationals.
