BEIRUT: The death toll in Syria's three-year war has eclipsed 170,000 people, one-third of them civilians, an activist group said in a new toll released Thursday.
"Ever since the first casualty of the Syrian revolution was registered on March 18, 2011 in Daraa province, the deaths of 171,509 people have been documented," said the Syrian Observatory for Human Rights.
Among the dead were 56,495 civilians, including 9,092 children, according to the toll, which included casualties documented up to July 8 this year.
Another 65,803 were regime troops and pro-regime militiamen, while 46,301 were rebels seeking President Bashar Assad's ouster and members of the Islamic State of Iraq and Greater Syria (ISIS) jihadist group.
The rebel toll includes 15,422 non-Syrians who traveled to the war-torn country to join the ranks of jihadists or local Islamist opposition groups.
Among the ranks of loyalists killed were 39,036 regular troops, as well as 24,655 members of pro-regime militias, 509 fighters from Lebanon's Shiite Hezbollah, and 1,603 other non-Syrians fighting on Assad's side in the war.
Meanwhile, the deaths of 2,910 unidentified victims were also documented, according to the Observatory.
The Britain-based group, which relies on a broad network of activists, doctors and lawyers inside Syria to document casualties, said the actual number of killed among fighters on both sides was likely to be much higher.
It said documenting all the deaths was difficult "because both sides in the war try to conceal their actual losses."
Another 20,000 people detained by the regime were completely unaccounted for, said the Observatory, as were some 7,000 regime troops held by rebel fighters.
More than 2,000 other people are currently in the captivity of Islamic rebels and ISIS, accused of "collaborating" with the Assad regime.
Another 1,500 ISIS, rebel and Kurdish fighters have been kidnapped in recent months during battles among each other.
The Syrian conflict has forced nearly half the country's population to flee their homes.
