(Foreign Policy) – A Saudi-led military coalition conducting airstrikes in Yemen committed “grave violations” of human rights against children last year, killing 502, injuring 838, according to a draft report by the U.N. Secretary General António Guterres. “The killing and maiming of children remained the most prevalent violation” of children’s rights in Yemen, according to the 41-page draft report obtained by Foreign Policy. “In the reporting period, attacks carried out by air were the cause of over half of all child casualties, with at least 349 children killed and 333 children injured.”
