At least 26 civilians were killed Monday in a jihadist-held village in northeast Syria in strikes likely conducted by a US-led coalition, the Syrian Observatory for Human Rights said.
"The raids struck the village of Al-Khan, which is held by the Islamic State group," said Observatory head Rami Abdel Rahman.
"But Daesh is only present on the outskirts of the town, which is why all of the deaths were civilians," Abdel Rahman said, using the Arabic acronym for ISIS.
The toll included seven children and four women, but was likely to rise as at least 17 people were unaccounted for and bodies were still being pulled out from under the rubble, he added.
Al-Khan lies near the village of Al-Hol in Syria's northeast Hasakeh province.
Kurdish and Arab rebel groups, backed by the US-led coalition bombing jihadists in Syria, recaptured Al-Hol from the Islamic State group last month.
The coalition began striking ISIS's Syria positions in September 2014, expanding its campaign from neighbouring Iraq.
A spokesman said he had no details yet on whether coalition aircraft had conducted strikes in the area on Monday, but said a "credibility assessment" would be launched to verify claims of civilian deaths.
