Jets believed to be Russian bombed several towns in rebel-held northwestern Syria in a new flare-up of violence since a Turkish-Russian deal that halted major fighting nearly six months ago, witnesses said.
War planes flying at high altitude, which tracking centres said were Russian Sukhoi jets, dropped bombs on the Harbanoush and Sheikh Bahr Nahr areas where makeshift camps house tens of thousands of displaced families.
"There were over 20 raids we have monitored by Russian jets stationed in Hmeimim air base," said Abdullah Sawan, a volunteer plane spotter whose network covers the Russian air base in the western coastal province of Latakia.
