Two Iranian officials indicated that Tehran encouraged the Houthis to stop targeting U.S. assets, aligning with Iran's interest in de-escalating tensions to advance nuclear negotiations. Here's the story from a piece at the Times of Israel:

Iran leaned on Yemen's Houthi rebel group to reach a truce with the US over attacks in the Red Sea in a move aimed at pushing along negotiations for an agreement over Tehran's nuclear program, according to reports.

US President Donald Trump on Tuesday evening announced an end to hostilities with the Houthis, catching Israeli officials by surprise. The announcement did not mention the ongoing Houthi missile and drone attacks on Israel, and officials for the Yemeni rebel group pledged that such strikes would continue.
