Airstrikes by US-led coalition fighter jets have killed at least 21 civilians in northern Syrian territories held by ISIL terrorists

Airstrikes by US-led coalition fighter jets have killed at least 21 civilians in northern Syrian territories held by ISIL terrorists, a monitoring group said.

The so-called Syrian Observatory for Human Rights said Monday that at least 15 people were killed as the coalition carried out raids in a northern district of Manbij city.

The UK-based group, which advocates the Syrian opposition, said six more people lost their lives in a village near Manbij after similar attacks by coalition fighter jets.

The so-called multinational task force against ISIL started its controversial mission in Iraq in late 2014 after ISIL seized control over territories west and north of the country. The United States claims the attacks are carried out to assist Syrian Kurds and Arabs fighting against ISIL in areas along the Turkish border in the province of Aleppo. However, the attacks have led to numerous deaths among the civilians and Syrian military forces.
The US and allies use the Incirlik  air base in southern Turkey to bomb purported ISIL positions in northern Syria and Iraq.
