The Iran-backed group said it has assured the Trump administration it won’t attack U.S. vessels in the Red Sea.

Saudi monarch’s rare condemnation hints at sense of urgency in the kingdom amid ramped-up attacks from Yemen.

The lightning advance of Yemen's Houthi rebels down the Red Sea coast was aided by Iranian advisers on the front lines.

The Houthis said the operation, which involved missiles and drones, came as a response to an attack in the Yemeni capital Sanaa.

The conflict has opened a second front in the Middle East after the United States and Israel attacked Iran, adding to global uncertainty and turmoil in energy markets.

SANAA: Yemen's Houthis said Saudi Arabia carried out a deadly strike on a key port city on Tuesday (Sep 22), over a week into the Houthi offensive that has seen them seize control of a strait that is crucial to global energy flows.

The split in Washington and London’s responses is exposing fresh fault lines among Saudi Arabia’s Western allies.

Britain will provide limited defensive military support to Saudi Arabia amid intensified Houthi missile and drone attacks. The RAF is expected to deploy a Voyager aircraft for air-to-air refuelling, while the UK says the mission will help protect regional energy routes.
