In September, the Pentagon said the Houthis had launched “a complex attack” on US Navy ships in the region, though all of the weapons launched were shot down.
As well as the attacks on ships in the Red Sea, the Houthis have fired several missiles and drones at Israel directly.
In July, a drone launched from Yemen struck Tel Aviv, killing one person and injuring 10. In September, the group fired several missiles at Israel, including one that targeted Israel’s main airport.
Both times Israel responded by attacking sites in Yemen.
Earlier this year, the US, UK and 12 other nations launched Operation Prosperity Guardian to protect Red Sea shipping lanes against the Houthis.
The Houthis are part of a network of armed groups in the Middle East backed by Iran that includes Hezbollah in Lebanon and Hamas in Gaza.
