Feature: Tensions simmer beneath surface calm in Yemeni capital as Red Sea on boil

SANAA, Jan. 18 (Xinhua) -- Despite the apparent calm on the surface of Sanaa, Yemen's capital under Houthi control, concerns and uncertainties loom larger as tensions in the Red Sea reach a new height.

Airstrikes by the United States and Britain on Houthi targets in northern Yemen in response to the Houthi attacks on Israel-related vessels in the Red Sea have not disrupted the daily routines of the city's over 3 million residents. They still go about their business, except for the frequent large Houthi-organized protests to support the Palestinians, which have become a common sight in the central part of the city.
