ANKARA, Sept 16 (Reuters) – The Houthi capture of ground overlooking the Bab el-Mandeb Strait has dealt Saudi Arabia its gravest setback in Yemen in years, exposing intelligence failures, the collapse of Yemeni allies and the limits of U.S. protection.
A Houthi advance this week along the Red Sea coast and the capture of islands at the mouth of the strait, a vital artery for global oil supplies, has also left the kingdom scrambling for backing as Iran and its allies expand their reach.
