SANAA (Reuters) - Saudi-led coalition warplanes struck government buildings controlled byHouthi fighters in the Yemeni capital Sanaa overnight and army units loyal to former president Ali Abdullah Saleh after at least 50 coalition soldiers were killed on Friday.

Among the targets, the Defense Ministry building in Sanaa was very heavily damaged, residents said. Strikes hit the command of the special security forces and camps of Saleh as well as the presidential complex.

At least 50 soldiers from the United Arab Emirates and Bahrain were killed in Yemen on Friday in the deadliest attack on Gulf Arab troops in the Saudi-led military campaign againstHouthi forces.
