Post Syrian truce, Russia raids Aleppo: Monitor

“The Russian and Syrian warplanes together carried out at least 40 air strikes on the Castello road,” Syrian Observatory for Human Rights chief Rami Abdel Rahman said.

“They are the heaviest air strikes there since February, and they are also the first confirmed Russian strikes since the truce began,” Abdel Rahman said.

The violence wracking Aleppo city over the past month has killed some 300 civilians and left world powers scrambling to save the fragile truce brokered by the United States and Russia nearly three months ago.

 The northern city - once Syria’s commercial powerhouse - is divided between rebel groups in the east and regime forces in the west. The Castello road is a key supply route for rebels leading north out of Aleppo.

Even while the rest of the city witnessed relative calm in the first few weeks of the truce, fierce fighting has raged for the highway.
