Beirut: Syrian army airstrikes killed at least 70 people, most of them civilians, and wounded scores in attacks in the northern province of Aleppo that struck civilian areas, including a packed market in a town held by the Islamic State group, activists said.
The deaths occurred in two separate incidents when helicopters dropped explosives-filled barrels yesterday. One barrel hit the rebel-held Shaar neighborhood of the city of Aleppo, killing at least 12 people, most of them from the same family. They included three children and four women, according to the Britain-based Syrian Observatory for Human Rights.
The other attack was far deadlier, hitting a busy market known as Souk al-Hal in the Islamic State-held town of al-Bab in Aleppo's countryside.
The Observatory said at least 59 people were killed and dozens wounded, calling it the one of the worst massacres perpetrated by President Bashar Assad's army this year. It said the number of dead likely would rise because many of the wounded were in critical condition.
The Local Coordination Committees reported more than 50 people killed and around 70 wounded in the al-Bab attack. Both groups document violence through a network of activists on the ground in Syria.
Al-Bab is controlled by the Islamic State group, which also confirmed the attack in a statement posted on Twitter. It said 50 people were killed in a "devastating massacre" committed by Syrian army helicopters.
The United Nations Special Envoy for Syria, Staffan de Mistura, strongly condemned the barrel -bomb attacks, in a statement released Sunday. He said such "indiscriminate" aerial attacks were responsible for "the overwhelming majority of the civilian victims in the Syrian conflict."
De Mistura said it is "totally unacceptable that the Syrian air force attacks its own territory in an indiscriminate way, killing its own citizens, as it brutally happened today in Aleppo."
Aleppo, once Syria's commercial hub, has been divided between government and opposition forces since mid-2012, and fighting there has raged since.
Government warplanes have dropped explosives-filled barrels on rebel-held neighborhoods, killing thousands while Syrian rebels have shelled residential areas in government-held parts of the contested city, killing hundreds.
The Syrian military has suffered a series of embarrassing setbacks in northern Syria recently as insurgents captured the city of Idlib and almost all of Idlib province. The Islamic State group has also pushed into central Syria, seizing the ancient city of Palmyra earlier this month after government forces fled the area.
