According to new Syrian Civil Defence Authority statistics, Russian air strikes have targeted Syrias opposition-held areas and killed 1,815 civilians.
In September, Russia had announced that its air strikes in Syria were aimed at combating DAESH in order to support its close ally, Syrian regime leader Bashar al Assad.
However, the Western powers and Turkey have consistently criticised Russia for targeting opposition forces rather than DAESH.
Russian air attacks have increased in the cities of Idlib, Aleppo, Hama, Homs, rural areas in Latakia, Daraa and southern Damascus.
Meanwhile, the Syrian Network for Human Rights (SNHR) published its report last month and declared that Russian fighter jets destroyed at least 16 schools, 11 hospitals, 10 mosques, eight industrial structures and several opposition headquarters that were used to fight against the Assad regime and DAESH.
The report said there is evidence showing that Russia "has unlawfully used unguided bombs in densely populated areas," such as on residential areas, homes, mosques and busy markets, as well as medical facilities.
