"As U.S. strikes on Syria expand, Human Rights Watch says a bombing last week on the town of Idlib should be investigated for possible violations of the laws of war. The strikes killed at least seven civilians, including five children, in the early morning hours of September 23 in the village of Kafr Deryan in northern Idlib province. Local activists at the scene of the attack collected and videotaped the remnants from the weapons used in the strikes. Human Rights Watch reviewed the footage and identified the remnants as debris of a turbofan engine from a Tomahawk cruise missile, a weapon that only the U.S. and British governments possess. "Witness accounts suggest that the attack on the village harmed civilians but did not strike a military target, violating the laws of war by failing to discriminate between combatants and civilians, or that it unlawfully caused civilian loss disproportionate to the expected military advantage," HRW details. The group has called on the U.S. government to investigate the allegations and publish its findings. We are joined by Nadim Houry, Human Rights Watch senior researcher for Lebanon and Syria...."
