The Syrian air force intensified its aerial campaign against rebel-held areas in Syria on Sunday, conducting a series of airstrikes on Aleppo, Daraa and Hama, killing 15 people, activists said.
The Syrian Network for Human Rights (SNHR) said at least six victims, including a woman and a child, were killed in barrel bomb attacks on the neighborhood of al-Sukkari in Aleppo.
A missile attack on the neighborhood of Tariq al-Sadd in the southern city of Daraa on Sunday also killed eight civilians, including three women.
Regime helicopters also dropped two barrel bombs on Kafr Zaita Specialist Hospital in Hama countryside, killing two medics, according to SNHR.
The Assad regime has waged an unrelenting aerial campaign against opposition-held areas over the past months, making particular use of improvised barrel bombs. Rights groups have heavily criticized the weapons, claiming they cause indiscriminate damage and are more likely to inflict civilian casualties.
