Missiles fired at US warships in Red Sea, no casualties — US official

WASHINGTON — Multiple missiles were fired on Saturday at three US warships in the Red Sea, though none was hit and there were no casualties, the US military said, amid rising tensions with Yemen's Houthi rebels.

A US defence official said the altercation took place starting around 1930 GMT. It was unclear how many of the surface-to-surface missiles were fired at the USS Mason, USS Nitze and USS Ponce.

The USS Mason destroyer, which was sailing in international waters off Yemen's coast earlier this week, used unspecified countermeasures against the incoming missiles, the official said.

The attempted missile strikes were the most serious escalation yet of America's involvement in a deadly civil war that has killed more than 6,800 people, wounded more than 35,000 and displaced at least three million since a Saudi-led coalition launched military operations last year.

Officials have stressed that Washington wants to avoid getting embroiled in yet another war in an already volatile region where America is to varying degrees waging wars in Afghanistan, Iraq, Libya and Syria.

On Thursday, the US Navy launched five Tomahawk cruise missiles at three mobile radar sites in Houthi-controlled territory on Yemen's Red Sea coast, after the Iran-backed rebels blasted rockets at the USS Mason twice in four days.

The military insists these moves are taken out of self-defence. The Houthis have denied conducting the attacks.

Though the United States is providing logistical support to a Saudi-led coalition battling the rebels, Thursday's launches marked the first time Washington has taken direct action against the Houthis.

But the US strikes earlier this week did not take out Houthi missiles and, though the radar destruction makes it harder to aim the weapons, officials have warned rebels could still use spotter boats or online ship-tracking websites to find new targets.

The rockets fired at the USS Mason on Sunday and again Wednesday were believed to be the first time since 1987 that a US warship has been targeted by an incoming missile.
