AFP, RIYADH: A Saudi soldier and a civilian have been killed in cross-border shelling from rebel-controlled northern Yemen, authorities said late Saturday. A Saudi patrol was hit on Saturday morning in the southwestern region of Assir, killing the soldier, the interior ministry said in a statement carried by state news agency SPA. Later in the day, the southwestern city of Najran was struck, leaving dead a foreign resident, a civil defence spokesman said in a statement on SPA. About 90 civilians and soldiers have died from shelling and skirmishes along the border since March, when a Saudi-led military coalition began air and ground action in Yemen. The coalition is backing Yemen government in a bid to push back Iran-backed Shiite Huthi rebels who overran Sanaa in September 2014.
