The Syrian fighter jets struck the Deraa Camp for Palestinian refugees with gas cylinders and mortar shells.
Nearly 80% of civilian buildings in the camp have been destroyed in the raging warfare.
Deraa residents have launched cries for help over the serious upshots of the tough blockade imposed by the Syrian regime troops on the camp and its environs, resulting in an acute shortage in foodstuff. Power and water supplies to the camps have also been cut off for long periods.
