The US military launched strikes on the Houthis, hitting 15 targets. The Pentagon used aircrafts and warships to launch the attacks to "protect freedom of navigation".
Several explosions were reported in some of Yemen’s main cities, including the capital Sanaa.
On Monday, the Houthis shot down a US-made MQ-9 Reaper drone over Yemen. The US military acknowledged losing an unmanned aircraft.
Last week the Pentagon said the Houthis launched "a complex attack" on US Navy ships in the region, though all of the weapons launched were shot down.
