Around 5,000 people were killed in Syria in August 2015 only, according to the Syrian Observatory for Human Rights, a UK-based monitor.
The number was as high as 4,830 according to sources within the country but the true total is suspected to be far higher.
The death toll includes 1,205 civilians, 885 Syrian combatants, 1,165 non-Syrian combatants, three "defected" soldiers, 684 Syrian army soldiers, 684 "militiamen," 36 Hezbollah fighters, 64 pro-regime Shiite militants and 10 unidentified victims seen on footage and photographs.
According to the data, 200 of the civilians were killed by ISIS, 1,000 by forces loyal to President Bashar al Assad and 43 in coalition air strikes battling ISIS.
A total of 252 children were killed in August.
"We in the Syrian Observatory for Human Rights estimates the real number of non-Syrian casualties from the IS [ISIS], Jabhat al- Nusra, Islamic factions, Jund Al-Aqsa battalion and pro-regime militants is approximately 700 soldiers and fighters more than the documented number because of reticence about casualties by all parties, the difficulties of reaching to the outback and the difficulties to investigate about those who have died inside the regime or IS jails," says the observatory report.
Much of the media focus covering Syria’s conflict recently has revolved around the destruction of the ancient ruins at Palmyra.
UNESCO, the UN’s cultural body, said on Tuesday, satellite images show that the most important site in the ancient Syrian city of Palmyra has been destroyed.
According to the images, the site of Bel Temple most likely was blown up by explosives on Aug. 30. Activists said ISIS had targeted the 2000-year-old temple.
The SOHR confirmed the Bel Temple reports as well.
Over 300,000 people have been killed in Syria since the start of the war in 2011, a number that may explain why many Syrians resort to immigration seeking safety in the West.
Most recently, Germany has said all Syrians who reach its border will be given the opportunity to stay and apply for asylum. Chancellor Angela Merkel has criticised other European nations for not doing as much to help in what has been called the worst migrant crisis since World War II.
