The emir of Kuwait, Sheik Jaber Al Ahmed Al Sabah, is recuperating in Switzerland after medical treatment in the United States, state television reported Wednesday. The prime minister, Sheik Sabah Al Ahmed Al Sabah, left Kuwait Wednesday to visit the emir, his half brother, in Switzerland, the TV reported. Sheik Sabah had said on the weekend that the emir was well and was going to Switzerland for convalescence. Sheik Jaber, 79, arrived in Zurich, Switzerland, on Monday. He had spent more than two months in the United States where he was operated on late May for a dilated blood vessel in his left leg. The emir suffered a brain hemorrhage in 2001. He has made few public appearances in recent years. Whenever he did appear, he spoke with difficulty and relied on support from his aides.
