The US military carried out more strikes in Yemen early on Wednesday, destroying two Houthi anti-ship missiles that were aimed at the Red Sea and were preparing to launch, the US military said in a statement.
The US strikes, which took place at roughly 2:30 am (2330 GMT), are the latest against the group over its targeting of Red Sea shipping and followed a larger round of strikes a day earlier.
The Houthis, who control the most populous parts of Yemen, have said their attacks are in solidarity with Palestinians as Israel strikes Gaza.
"US forces identified the missiles in Houthi-controlled areas of Yemen and determined that they presented an imminent threat to merchant vessels and the US Navy ships in the region," the US military's Central Command said in a statement.
"US forces subsequently struck and destroyed the missiles in self-defence."
Since the US started striking Houthi military sites in Yemen on January 11, the Pentagon says it has destroyed or degraded over 25 missile launch and deployment facilities and more than 20 missiles.
It says it has also struck drones, coastal radar and Houthi air surveillance capabilities as well as weapon storage areas.
"We have been very focused on targeting the kinds of things that they've been employing or using to conduct attacks against international shipping and mariners, and that will continue to be our focus," Pentagon spokesperson Major General Patrick Ryder told a news briefing on Tuesday.
Ryder noted that the last Houthi attack was on January 18, suggesting the strikes were having an impact.
"Since that time we have taken several self-defence strikes, when there was an imminent threat or an anticipated launch," he said.
