The so-called Syrian Observatory for Human Rights documented in a new report released on Tuesday that the total deaths resulting from the ongoing crisis in Syria amounted to 150,344 people, of which 51,212 were civilians, including 7,985 children.
The report said 37,781 members of the armed opposition had been killed, including militants from the so-called Islamic State of Iraq and the Levant (ISIL) and the al-Qaeda affiliated al-Nusra Front.
A total of 58,480 government forces, including more than 35,000 soldiers, were also killed.
An additional 2,871 people died but their identities remained unknown, the group added.
Syria has been gripped by deadly violence since March 2011. The West and its regional allies have been fuelling the unrest by providing militants with money and weapons.
