"Closer attention should be focused on reports from the Syrian side about indiscriminate coalition airstrikes in the east of Euphrates which claimed dozens of lives," Safronkov said on Monday. "These need to be investigated."
The US-led coalition also said in a statement on Saturday it had detected 10 non-coalition strikes in Deir ez-Zor. Pentagon spokesperson Robert Manning said during a press briefing on Monday that ten unidentified strikes in eastern Syria over the weekend are suspected to come from Syrian and Iran-backed forces.
On Thursday, the Syrian news agency SANA reported that 23 civilians were killed in coalition airstrikes in Deir ez-Zor. According to the news agency, the strikes targeted the residential areas of the villages of Bu-Badran and al-Sousa.
The coalition regularly carries out airstrikes in the Syrian eastern province. On November 9, media reported that 26 civilians, including women and children, were killed in an airstrike by the coalition on the city of Hajin.
