BEIRUT - US-led coalition airstrikes on the last pocket held by Islamic State militants in Syria near the Iraqi border killed at least 40 people, mostly women and children, a war monitor and Syrian state media reported.

The coalition confirmed strikes in the area but said no "civilian casualties are associated" with them, reiterating that it takes measures to avoid noncombatant casualties.

"We have witnessed (IS) using places of worship and hospitals as command centers against the laws of war, and innocent civilians as human shields," said Sean Ryan, a spokesman for the coalition.

The remote area near the border with Iraq is difficult to access and it was not possible to independently verify the reports.

However, Rami Abdurrahman, head of the Britain-based Syrian Observatory for Human Rights, said the airstrikes early on Saturday hit homes in Abu al-Hassan village, near the town of Hajin, which lies along the border with Iraq.

Abdurrahman said the airstrikes killed at least 43 people, including 17 children and 12 women. He said it was not immediately clear if the men killed in the strikes were militants.

Syrian state news agency SANA also reported the strikes, saying 40 were killed in the remote area of Buqaan, another village next to Abu al-Hassan, in Deir el-Zour province.

The IS-linked Aamaq news agency also reported 40 killed, quoting a medical official in the Hajin area.

Activist Omar Abou Leila, who monitors the war in Deir el-Zour from Europe, also confirmed the strikes but said it was difficult to verify the death toll. Abou Leila said IS militants are preventing civilians from leaving the area, resulting in the high casualty toll among them.

The US-led coalition and its local partners on the ground, the Kurdish-led Syrian Democratic Forces, launched the campaign against the last IS-held pocket in early September.

The Observatory has recorded at least 191 civilians killed since Sept 10, including 65 children and 45 women. They are mostly Iraqis and believed to include family members of IS militants.

Speaking to The Associated Press in Iraq on Saturday, the coalition's Deputy Commander Major General Christopher Ghika described the fight against the IS group as "difficult".
