Forces loyal to President Bashar al-Assad have been besieging almost 400,000 civilians trapped inside Eastern Ghouta for years, but the siege has tightened this year and attacks on the enclave have intensified.
Pro-government forces carried out air raids on Eastern Ghouta overnight on Monday and early on Tuesday, the British-based Syrian Observatory for Human Rights said.
More than 100 people were killed in air raids, rocket strikes and shelling of the area on Monday, it added.
