The conflict in Yemen has killed nearly 7,700 people, including at least 1,564 children, since a Saudi-led coalition intervened on the government's side two years ago, UN agencies said Monday. The UN children's agency UNICEF said that by March 10, at least 1,546 children were killed and 2,450 others maimed in Yemen. Of those killed, 1,022 were boys and 478 were girls while 46 were of "unknown sex", UNICEF said in a statement. During that same period 1,801 boys and 649 girls were wounded while 1,572 boys were recruited to serve as child soldiers, said UNICEF.
