At least ten civilians – including at least one woman and two children – were killed and dozens more were wounded following airstrikes near two schools in the city of Al Mayadeen. However, local sources were conflicted as to who was responsible. Both Russia and the US-led Coalition were reportedly responsible. Syrian Network for Human Rights blamed the Syrian Regime.

Nine of the 13 sources reporting the incident did not make any allegations as to who was responsible given the difficulty in identifying perpetrators (given that Coalition, Russian and Syrian government warplanes were all operating in the vicinity.)

Euphrates Post reported that the warplanes responsible were unidentified, but that they “probably belonged to the Russian air force”. Further sources, including Syria News Desk, @Syrian_Revolution and Deir Al Zor PN, directly alleged that Russia was responsible.

Meanwhile Step News Agency claimed the Coalition was to blame while the Syrian Network for Human Rights said the Syrian government was responsible.

Euphrates Post, among a number of other local sources, reported that the strikes hit civilian areas near the Al Nasswi School and the Khawla Bint Azwar School and that most of the damage was caused to the homes of Muhanned Hamoud al Hamran and Allawi al Helou.

The source added that the airstrikes caused “burning of two civilian vehicles and material damage to a number of shops and adjacent residential buildings”.

DeirEzzor24 reported that “the number [of civilian casualties] is likely to rise due to the large number of wounded and the lack of medical personnel” and added that “the search for survivors from the rubble is still ongoing”.

Many sources described the incident as a “massacre”.
