(CNN) -- Syria's air force has repeatedly carried out "indiscriminate, and in some cases deliberate" airstrikes against civilians, Human Rights Watch said in a new report. The attacks are serious violations of international humanitarian law, and those who commit such violations with criminal intent are responsible for war crimes, the rights group said. The claims are laid out in an 80-page report titled "Death from the Skies," based on visits to 50 sites of government airstrikes in opposition-controlled areas in Aleppo, Idlib and Latakia provinces. The group's researchers carried out more than 140 interviews with witnesses and victims. "In village after village, we found a civilian population terrified by their country's own air force," said Ole Solvang, a researcher for the rights group, who visited the sites and conducted many of the interviews.
