Baghdad - About 18 civilians, mostly Iraqi refugees, were killed Monday in an airstrike launched by warplanes of the U.S.-led international coalition on Khoibra village in the southern countryside of Hasaka, Syria.

Local sources told Syria's SANA news agency that the warplanes of the international coalition raided a school in the village of Khoibra, southeast of al-Shadadi, claiming the lives of 18 civilians, most of them are Iraqi refugees who fled from criminal acts of Islamic State and the coalition's bombing.

In April, Iraqi Prime Minister Haidar al-Abadi denied intentions to interfere in the domestic affairs of Syria, saying airstrikes against Islamic State will continue.

Iraq had previously announced launching airstrikes against IS locations in Syria. This came after Abadi said security troops will follow IS militants in the whole region, not only in Iraq.

The Iraqi-Syrian borders are under the control of joint troops of military and border guards.

Islamic State continues to launch sporadic attacks across Iraq against troops. Security reports indicate that the militant group still poses threat against stability in the country.

Abadi announced, in December, full liberation of Iraqi lands, declaring end of war against IS members.
