Russian warplanes hit a key rebel supply route to Aleppo on Sunday in Moscow's first strikes on Syria's battleground second city since a February ceasefire, a monitoring group said, according to AFP.
"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."
