According to the coalition, the reports of the deaths of the civilians due to the airstrikes in Hajin are under investigation.
"We've heard claims of strikes in Hajin reportedly killing civilians. As part of the stringent planning process in identifying ISIS [Daesh] targets, we take extraordinary measures to avoid civilian casualties and take all instances of civilian casualties seriously. This incident is currently under investigation," the coalition's spokesperson said.
In the meantime, the Syrian Foreign Ministry has reportedly sent two letters to the United Nations over the deadly airstrikes, carried out by the US-led coalition.
The ministry called on the UN Security Council to take "serious and immediate" steps toward non-repetition of such attacks, and also to create an independent international mechanism for the investigation into such incidents.
Earlier in November, the Syrian Arab News Agency (SANA) reported that the coalition carried out airstrikes in the region using white phosphorus munitions, which are banned under the 1977 First Additional Protocol to the 1949 Geneva Conventions.
