WASHINGTON—The U.S., Britain and key allies issued what officials described as a final warning to the Houthi Yemeni rebel group Wednesday to cease its attacks on international shipping in the Red Sea or bear the consequences.

“Ongoing Houthi attacks in the Red Sea are illegal, unacceptable, and profoundly destabilizing,” says the statement issued by more than a dozen nations. “The Houthis will bear the responsibility of the consequences should they continue to threaten lives, the global economy, and free flow of commerce in the region’s critical waterways.”
