For weeks, US airstrikes have pounded Houthi targets in Yemen, hitting oil refineries, airports and missile sites, with President Trump vowing to use “overwhelming force” until the US achieves its goal of stopping the Houthis from targeting shipping in the Red Sea.

Suspected U.S. airstrikes killed at least two people overnight in a stronghold of Yemen 's Houthi rebels, the group said Sunday, as a bombing video posted by U.S. President Donald Trump suggested casualties in the campaign may be higher than the rebels acknowledge.
