Houthis say U.S., UK strikes won't go unpunished

STORY: He added the attacks would not go without "punishment or retaliation" and that the group will continue to target ships headed for Israel.

The Houthis, an armed movement that took control of most of Yemen over the past decade, have been attacking shipping at the mouth of the Red Sea - one of the world's busiest trade lanes - since October. The action is in support of Hamas, they say.

Witnesses in Yemen confirmed explosions throughout the country, saying raids targeted a military base adjacent to Sanaa airport, a military site near Taiz airport, a Houthi naval base in Hodeidah and military sites in Hajjah governorate.
