At least five air strikes hit military sites and an area near the presidential palace compound in the Yemeni capital Sanaa at dawn on Sunday while warships pounded an area near the port of the southern city of Aden, residents said. The bombings were the first raids on Sanaa since a Saudi-led alliance said last week it was scaling back a campaign against Iranian-allied Houthi militias. "The explosions were so big they shook the house, waking us and our kids up. Life has really become unbearable in this city," a Sanaa resident who gave his name as Jamal told Reuters.
