Nov. 13 (UPI) -- Airstrikes on a busy market killed dozens of people in the rebel-held town of Atareb, Syria, human rights activists said Monday.
It's unclear if Russian or Syrian planes carried out the strike, Britain-based Syrian Observatory for Human Rights said.
The organization said at least five children and three police officers died.
Atareb is located in part of Aleppo province where Russia, Iran and Turkey designated a de-escalation zone earlier this year. Two weeks ago, the three countries announced plans to make these areas no-fly zones. Hostilities against the Islamic State and Hay'et Tahrir al-Sham militant groups are excluded from the agreement.
Though there has been a drop in violence in these zones, clashes have occurred.
