Bloomberg News is reporting U.S. officials are in talks with pro-government militias in Yemen about a possible ground offensive to oust Houthi fighters from the Red Sea coast. U.S. aerial attacks on Yemen since mid-March have killed at least 123 people, as Houthis vow to continue targeting ships in the region that are tied to Israel’s war on Gaza.

Last week, a group of Democratic lawmakers called on the Trump administration to halt its attacks on Yemen, citing the War Powers Resolution, which requires congressional approval, or a declaration of war, to directly attack another country.
