Ammon News - U.S. President Donald Trump launched large-scale military strikes against Yemen's Iran-aligned Houthis on Saturday over the group's attacks against Red Sea shipping, killing at least 31 people at the start of a campaign expected to last many days.

Trump also warned Iran, the Houthis' main backer, that it needed to immediately halt support for the group. He said if Iran threatened the United States, "America will hold you fully accountable and, we won't be nice about it!"

The unfolding strikes - which one U.S. official told Reuters might continue for weeks - represent the biggest U.S. military operation in the Middle East since Trump took office in January. It came as the United States ramped up sanctions pressure on Tehran while trying to bring it to the negotiating table over its nuclear program.

At least 31 were killed and 101 others injured in the U.S. strikes, mostly from women and children, Anees al-Asbahi, spokesperson for the Houthi-run health ministry said in an updated toll on Sunday. Reuters
