A Russian airstrike on Syrian city Aleppo killed eight civilians on Saturday, a civil defense source said.

The jets targeted the opposition-controlled neighborhood of al-Sakhour, wounding scores more, the source told Anadolu Agency on condition of anonymity due to fear of reprisal. Civil defense volunteers ferried the casualties to nearby field hospitals.

Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on pro-democracy protests.
