The fatalities were caused after warplanes targeted areas in Daham village near Suluk in the northeastern countryside of Raqqah on Friday, the so-called Syrian Observatory for Human Rights said; Press TV reported.

The UK-based group said that the death toll was expected to rise because there were some people in critical situation.

Raqqah, on the northern bank of the Euphrates River, was overrun by the Takfiri terrorists in March 2013, and was proclaimed the center for most of the terrorists’ administrative and control tasks the next year.

The attack is not the first US-led airstrike that leads to civilian casualties.

Earlier this month, some 20 civilians were killed and 40 others injured when US-led jets struck the majority Kurdish village of Thulthana in the northern province of Aleppo.

Since 2014, the United States, along with a number of its allies, has been leading a so-called anti-terror campaign in Syria and neighboring Iraq.

Syria has been the scene of a foreign-backed crisis since March 2011.

A fresh round of talks opened in the Swiss lakeside town of Lausanne on Saturday, the latest attempt at international level, to find ways of putting an end to more than five years of conflict in Syria.
