Air raids by Syrian government warplanes killed at least 28 civilians, including 10 children, near Damascus on Thursday, the Syrian Observatory for Human Rights monitor said, according to AFP.
At least 60 others were also wounded in the raids on Hammuriyeh and Irbin in Eastern Ghouta, the largest rebel stronghold in Damascus province, the organization said.
20 of the dead, including eight children, were killed in Hammuriyeh, while another six people, among them two children, died in nearby Irbin.
The area is regularly bombed by the forces of President Bashar Al-Assad, Observatory director Rami Abdel Rahman told AFP.
But the world has mostly been silent as the attacks on this region continue. In August, the Syrian government carpet bombed the area, in an attack which caused the deaths of at least 100 people.
The Eastern Ghouta region was also the target of a chemical attack in 2013, following which President Barack Obama threatened military action against Syria, before Syria agreed to a diplomatic deal brokered by Russia that saw the Assad regime hand over its declared chemical weapons stockpiles.
More than 250,000 people have been killed in Syria's conflict, which began in March 2011 as an anti-government protest movement but has spiraled into a multi-sided war.
The regime has also been accused of using barrel bombs, containers packed with explosives and scrap metal that are typically dropped from helicopters, against civilians.
Assad has repeatedly denied using barrel bombs and has claimed in interviews that no such weaponry exists. The West, for its part, notes that only the regime has helicopters from which these weapons are dropped.
