Air strikes have killed dozens of people in a village controlled by Islamic State (IS) militants in eastern Syria, the Syrian Observatory for Human Rights monitoring group reported.
The London-based group said the air strikes hit the village of Al-Quria in the Deir al-Zor Province on June 25, killing 47 people including 31 civilians.
The group said it was not immediately clear whether the 16 others were civilians or IS fighters.
It was also unclear whether the air strikes were carried out by Syrian or Russian warplanes.
IS militants control most of Deir al-Zor Province and have laid siege since March last year to the remaining government-held areas in the city of the same name, which is close to Syria's eastern border with Iraq.
Russian warplanes have been carrying out an air campaign in support of President Bashar al-Assad since September 2015.
