Human Rights Watch says Syria is carrying out "unlawful" deliberate and indiscriminate attacks against civilians, and is urging the international community to pressure the government to stop.
The group released a report Thursday describing 59 air strikes in opposition areas of Aleppo, Idlib and Latakia between August and December last year. Human Rights Watch says those attacks - some hitting bakeries and hospitals killed 152 civilians, and appear to be part of a systematic campaign that amounts to crimes against humanity.
The report says the air strikes included the use of unguided bombs, fighter jets and high-flying helicopters without the ability to tell the difference between civilians and combatants on the ground.
Additionally, Human Rights Watch says four Syrian Air Force defectors told the group that they lacked the technology to "identify and target specific military objectives in urban areas."
