BEIRUT — Activist groups said Sunday that about 5,000 people were killed in Syria’s civil war in August, the highest figure ever reported in more than 17 months of fighting as President Bashar Assad’s regime unleashed crushing air power against the revolt for the first time.
The U.N. children’s fund UNICEF put the death toll for last week alone at 1,600, the largest weekly figure for the entire uprising. The number includes children.
“The past month witnessed large massacres, and the regime was conducting wide operations to try to crush the uprising,” said Omar Idilbi, a Cairo-based activist with the Local Coordination Committees group. “Last month’s acts of violence were unprecedented.”
The civil war witnessed a major turning point in August when Assad’s forces began widely using air power for the first time to try to put down the revolt. The fighting also reached Syria’s largest city, Aleppo, which had been relatively quiet for most of the uprising.
The Britain-based activist group Syrian Observatory for Human Rights said that 5,440 people, including 4,114 civilians, were killed in August. The LCC put the toll at 4,933 civilians.
The Observatory and the LCC said more than 100 people were killed throughout Syria on Sunday, and the groups have been reporting 100 to 250 deaths per day over the past week.
The two main activist groups also released new death tolls for the entire uprising since March 2011. The Observatory said more than 26,000 have been killed, including more than 18,500 civilians. The LCC put the death toll at more than 23,000 civilians.
The LCC does not count members of the military who are killed, but the Observatory does.
That averages out to about 1,300 to 1,500 deaths per month, making the August figure more than three times higher than average.
The groups had previously reported a toll of about 20,000 more than a month ago.
On Thursday, Human Rights Watch said government forces have killed scores of civilians over the past three weeks by bombarding at least 10 areas where they were lining up to buy bread at bakeries near and around Aleppo.
Last week, activists reported that between 300 and 600 people were killed in the Damascus suburb of Daraya during days of shelling and a killing spree by troops who stormed the town after heavy fighting.
“The reason behind the high death toll is military operations, shelling, clashes and air raids,” said Rami Abdul-Rahman, who heads the Observatory.
“I would say most people are being killed during clashes and executions,” he said, referring to scores of bodies that are found in streets around Syria who are shot execution style with a bullet in the back of their heads.
