A Russian-backed regime onslaught in northern Syria was reported Wednesday to have killed more than 500 people this month, as Turkey faced new pressure to open its border to people fleeing the violence, AFP reports.
The Syrian Observatory for Human Rights said 506 people had died since the regime launched a major offensive against rebels in Aleppo province on February 1.
They include 23 children who were killed in Russian air strikes, according to the Britain-based monitor, which relies on a network of sources on the ground.
Tens of thousands of Syrians were still stranded Wednesday at the Oncupinar border crossing, which remained closed.
