Two missiles have been fired at a US warship in the Red Sea off Yemen, the Pentagon says, the second such incident within days.
It is believed the missiles were fired from territory controlled by Iranian-backed Houthi rebels.
The Pentagon said the USS Mason, a guided-missile destroyer, took defensive action and suffered no damage. It gave no further details.
Officials say the US is weighing what military response to take.
“These unjustified attacks are serious, but they will not deter us from our mission,” said the chief of naval operations, Admiral John Richardson.
“The team in USS Mason demonstrated initiative and toughness as they defended themselves and others against these unfounded attacks over the weekend and again today. All Americans should be proud of them.”
It was not clear if the ship’s countermeasures caused the missiles to miss or if they would have landed in the water anyway.
On Sunday, two missiles were fired at the USS Mason from the same rebel-held territory.
Both hit the water before reaching the ship, the Pentagon said.
At the time, a Houthi spokesman told the Saba news agency that it had not targeted any warships.
A Saudi-led multinational coalition, supported by the US, is carrying out an air campaign against the Houthi movement.
The UN says at least 4,125 civilians have been killed and 7,207 injured since the coalition intervened in the conflict between forces loyal to Yemen’s internationally-recognised government and those allied to the Houthis in March 2015. BBC News
