Rights group says airstrikes by Saudi-led coalition killed many civilians in Yemen rebel city

Human Rights Watch says in a new report that airstrikes carried out by the Saudi-led coalition on Saada city in northern Yemen killed dozens of civilians in an apparent violation of the laws of war. The city is controlled by Shiite rebels.

The rights group said Tuesday its investigators visited on May 15-16 during a humanitarian cease-fire and compiled the names of 59 people killed in aerial attacks, including at least 35 children. It said satellite imagery showed more than 210 impact locations in built-up areas consistent with aerial bombings.

Human Rights Watch says many airstrikes were directed at legitimate military targets but several "appeared to violate international humanitarian law ... and resulted in numerous civilian deaths and injuries."

The group calls on the coalition to investigate all alleged violations.
