The Syrian Observatory for Human Rights reported that “warplanes believed to belong to the International Coalition bombed places in the Kdieran area which is located in the western countryside of al-Raqqa. There is information about casualties and damage to the property of the citizens.”
Both Qasioun and Sohaib_heskayi reported the Coalition “destroyed the Al-Hamdawi mosque” but didn’t mention civilian casualties.
In January 2019, the Coalition announced that it had classed the event as non credible due to a lack of available evidence of civilian harm: “After a review of available information and strike video it was assessed that there is insufficient evidence to find civilians were harmed in this strike.”
The local time of the incident is unknown.
