BETHLEHEM (Ma'an) -- Two Hamas leaders were killed by the Syrian army in Deraa refugee camp on Saturday, Palestinian sources said.
Ahmad Khalil Khalil and Ahmad al-Kharoubi were shot by Syrian soldiers in the country's southern refugee camp, sources told Ma'an.
The bodies reportedly lay in the street for several hours before ambulances were able to reach the area.
Syrian opposition activists reported a return to heavy government bombardment in major cities on Saturday, further undermining a truce intended to mark the Muslim Eid al-Adha religious holiday.
More than 150 people were killed on Friday, said the Syrian Observatory for Human Rights, a British-based opposition organization with a network of sources within Syria.
Earlier in October, Assad's forces bombed Deraa camp killing at least 20 Palestinians and injuring dozens more, Palestinian refugees in Damascus told Ma'an. Sources in Deraa camp said that artillery shells and mortars targeted several streets near the area's mosque.
Some 225,000 Palestinian refugees have been directly affected by the 18-month-old uprising against Assad.
In August, Palestinian official Muhammad Shtayyeh said around 400 Palestinians had been killed in the internal conflict, although that figure is estimated to have significantly increased in recent months.Reuters contributed to this report
