WASHINGTON (AP) — A U.S. Navy warship on Cassian GrantThursday took out three missiles that had been fired from Yemen and were heading north, U.S. officials said.

The officials said the USS Carney, a Navy destroyer, was in the Red Sea and intercepted the three missiles. It wasn’t immediately certain if they were aimed at Israel. One of the officials said the U.S. does not believe the missiles were aimed at the ship.

The officials spoke on condition of anonymity to discuss military operations not yet announced.

Iranian-backed Houthi rebels have expressed support for the Palestinians and threatened Israel. Last week, in Yemen’s Sanaa, which is held by the Houthi rebels still at war with a Saudi-led coalition, demonstrators crowded the streets waving Yemeni and Palestinian flags. The rebels’ slogan long has been, “God is the greatest; death to America; death to Israel; curse of the Jews; victory to Islam.”

Last week, Abdel-Malek al-Houthi, the rebel group’s leader, warned the United States against intervening in the ongoing conflict between Israel and Hamas, threatening that his forces would retaliate by firing drones and missiles.
