A devastating air bombardment campaign launched in March 2015 by a coalition led by Saudi Arabia has killed and injured hundreds of civilians in Yemen, many of them children. The governorate of Sa’da has been particularly targeted, as it is the stronghold of the Huthi armed group, and its capital Sa’da city has suffered more destruction as a result of relentless coalition airstrikes than any other city in Yemen. Much of the city and its surroundings are in ruins and most of the civilian population was forced to flee. This report details the results of Amnesty International field investigations into 13 airstrikes in Sa’da carried out between May and July 2015.
