Cairo: Yemen's Iran-backed Houthi rebels claimed responsibility for a series of deadly attacks this week, escalating the conflict between them and Saudi-backed Yemeni forces and raising fears of a wider regional conflagration.
The attacks have killed dozens of civilians and troops and also targeted Saudi tankers in transit from Red Sea ports through the Bab el-Mandeb Strait out to the Gulf of Aden and the rest of the world.
