TEHRAN (Press Shia Agency) – The so-called US-led coalition has killed as many as 3,222 civilians, among them 768 children and 562 women, since its operations began in Syria in 2014, a war monitor reported Tuesday.

The US-coalition has reportedly entered the battles in Syria against the ISIL in 2014, with the Syria government questioning the intention of the US and branding its intervention as illegal as it happened without the consent of the Syrian administration.

The Syrian Foreign Ministry has recently urged the UN to conduct an international investigation into the "crimes" of the US-led coalition.

Its latest calls came after the Syrian government repeatedly urged the international community to dissolve the US coalition, Xinhua reported.

The coalition has been supporting the Kurdish-led Syrian Democratic Forces (SDF) in their fight against the ISIL on the eastern bank of the Euphrates River in the eastern countryside of Deir Ezzor.

The attacks focused on the last ISIL-held pocket, with the SDF making progress in the current battle that has started over a month ago to eradicate the ISIL from that oil-rich region near the Iraqi border. The US-led coalition has killed as many as 3,222 civilians since its operations started in Syria in 2014, a war monitor reported Tuesday.

A total of 768 children and 562 women were among those killed by the strikes of the US-led coalition in the northern provinces of Hasakah, Raqqa, Aleppo, Idlib and the eastern province of Deir Ezzor, said the Syrian Observatory for Human Rights.

The latest attacks by the US coalition were reported on Saturday when the state news agency SANA said 63 civilians had been killed within 24 hours as a result of the US-led strikes on areas controlled by Daesh (ISIL or ISIS) in the eastern countryside of Deir Ezzor.
