RNA - The so-called Syrian Observatory for Human Rights said Wednesday that 6004 people had been killed in coalition airstrikes in Syria during a period of 23 months, from September 23, 2014 to August 23, 2016.
Of the total figure released, 599 people were civilians, according to the pro-opposition group.
Some 163 children were also among the civilians killed in the coalition airstrikes.
The report further said that hundreds of people, most of them Daesh Takfiri militants, had been also injured in the air attacks.
The so-called multinational task force against Daesh started its controversial mission in Iraq in late 2014 after Daesh seized control over territories west and north of the country. The air campaign was later expanded to cover areas in northern Syria despite criticism from the Syrian government that the attacks violate the sovereignty of the Arab country.
The United States claims the attacks are carried out to help Syrian Kurds and Arabs fighting against Daesh in areas along the Turkish border in the province of Aleppo. However, the attacks have resulted in numerous deaths among the civilians and Syrian military forces.
Syria has been gripped by foreign-backed militancy since March 2011. UN Special Envoy for Syria Staffan de Mistura estimates that over 400,000 people have been killed in the conflict.
