Syrian regime and allied forces on Tuesday (March 7th) retook a pumping station that supplies water to Aleppo from the "Islamic State of Iraq and the Levant" (ISIL), AFP reported.

"Regime forces took over the area of al-Khafsa and seized the water-pumping station after the withdrawal of ISIL," said Syrian Observatory for Human Rights head Rami Abdel Rahman.

ISIL fled in the face of a Syrian regime and allied offensive, he said.

Al-Khafsah pumping station provides the water supply for Aleppo, and residents of the regime-held city had been without mains supplies for some 50 days since ISIL cut it.

The regime offensive in Aleppo province has involved heavy air strikes and shelling and prompted an exodus of civilians, with the UN reporting that at least 26,000 people have fled since February 25th.

Meanwhile, two people were killed Wednesday in a bombardment of a Syrian opposition bastion near Damascus, less than 24 hours after a ceasefire was announced.

"A young man and a woman were killed in air strikes on Douma," the largest town in the Eastern Ghouta region, Abdel Rahman said.

Raids also hit the town of Arbin, and regime artillery hit Harasta, leaving nearly two dozen people wounded in Eastern Ghouta.
