DUBAI, United Arab Emirates (AP) — Suspected U.S. airstrikes have killed at least two people overnight in a stronghold of Yemen’s Houthi rebels. That’s according to reports by the Houthis on Sunday. The strikes in Saada wounded nine others. Footage aired by the Houthis’ al-Masirah satellite news channel showing a strike collapsing what appeared to be a two-story building. The Iranian-backed Houthis aired no footage from inside the building, which they described as a solar power shop. The intense campaign of airstrikes in Yemen under U.S. President Donald Trump has reportedly killed at least 69 people. A bombing video posted online by Trump suggests casualties in the campaign may be higher than the rebels acknowledge.
