The United States has carried out near daily strikes against the Houthis, who control the most populous parts of Yemen and have said their attacks on shipping are in solidarity with Palestinians as Israel strikes Gaza.
The months of attacks by Houthis have continued and have upset global trade and raised shipping rates.
A joint statement from countries that either took part in the strikes or provided support, said the military action was against 18 Houthi targets across eight locations in Yemen including underground weapons and missile storage facilities, air defence systems, radars and a helicopter.
US Defense Secretary Lloyd Austin said the strikes were meant "to further disrupt and degrade the capabilities of the Iranian-backed Houthi militia."
"We will continue to make clear to the Houthis that they will bear the consequences if they do not stop their illegal attacks, which harm Middle Eastern economies, cause environmental damage and disrupt the delivery of humanitarian aid to Yemen and other countries," Austin added.
Earlier this week the Houthis claimed responsibility for an attack on a UK-owned cargo ship and a drone assault on an American destroyer, and they targeted Israel's port and resort city of Eilat with ballistic missiles and drones.
The group's strikes are disrupting the vital Suez Canal trade shortcut that accounts for about 12% of global maritime traffic, and forcing firms to take a longer, more expensive route around Africa.
No ships have been sunk nor crew killed during the Houthi campaign. However, there are concerns about the fate of the UK-registered Rubymar cargo vessel, which was struck on February 18 and its crew evacuated.
