Houthis report 18 airstrikes in Yemen

In the latest response, U.S. and British forces carried out strikes at eight different locations in Yemen, with support from Australia, Bahrain, Canada and the Netherlands, according to a joint statement signed by the six countries.

A senior U.S. military official, speaking on condition of anonymity, said roughly 25 to 30 munitions were fired, some of them from warplanes launched from a U.S. aircraft carrier, Reuters reports.

So far, eight rounds of strikes over the past month have failed to stop Houthi attacks against shipping.

The Houthis' military spokesman, Yahya Sarea, said on January 23 that the U.S.-British alliance had carried out 18 air strikes: 12 in the capital Sanaa, three in the port city of Hodeidah, two in Taiz and one in Al-Bayda province.

"These attacks will not go unanswered or unpunished", he said.

U.S. officials say the strikes have degraded the Houthis' ability to carry out complex attacks. But they have declined to offer any specific numbers of missiles, radar, drones or other military capabilities destroyed so far.

"We are having the intended effect," the U.S. military official told Pentagon reporters.
