DAMASCUS, June 12 (Xinhua) -- At least 12 civilians of the same family were killed by renewed U.S.-led airstrikes on Syria's northeastern province of al-Hasakah on Tuesday, state news agency SANA reported.

The airstrikes targeted the village of Tal Shayer in the southeastern countryside of al-Hasakah, the latest in a string of airstrikes that have caused civilian casualties.

A day earlier, the U.S.-led coalition killed 18 civilians, mostly Iraqi refugees, in airstrikes on the town of Khoeberah in the southern countryside of al-Hasakah, said SANA, adding that women and children were among the killed.

The attacks came after 10 civilians, mostly women and children, were killed last Tuesday in the U.S.-led airstrikes on the town of Jaza'a in the southern countryside of al-Shaddadah city in al-Hasakah province.

SANA said the U.S.-led coalition is ramping up airstrikes on the southern countryside of al-Hasakah to enable the Kurdish-led Syrian Democratic Forces (SDF) to take control.

The U.S. and the SDF have been on an offensive against positions of the Islamic State (IS) militant group in al-Hasakah to consolidate the Kurdish control in areas east of the Euphrates River.

The Syrian government has slammed the killing of civilians by the U.S.-led coalition, calling it an "illegitimate" coalition that should be disbanded.
