Yemen Truce Starts After Shelling

Saudi-led air strikes hit the rebel-held Yemeni capital Sanaa hours before a five-day humanitarian truce took effect on Tuesday, and Washington cautioned against "provocative actions" after Iran dispatched a cargo ship to Yemen. The ceasefire began at 11 p.m., said Brigadier General Ahmed Asseri, spokesman for a Saudi-led coalition that has been striking Yemen's Houthi rebels since March 26, but clashes persisted after that in some areas. It is intended to allow the shipment of food and medicine to the country, which aid groups warn faces a humanitarian catastrophe after more than seven weeks of war but it will end if the Houthis do not also lay down arms.
