Yemane’s Ansarullah movement has stated it plans more attacks on United States and British warships.

In a statement released on Wednesday, it said all U.S. and British warships participating in “aggression” against Yemen are targets. 

The Ansarullah, who control the most populous parts of Yemen, have launched drones and missiles at Israeli-affiliated shipping in the Red Sea and Gulf of Aden since November 19. 

The group said the attacks are a response to Israel’s military operations in Gaza. 

The U.S. and Britain have struck back at Ansarullah targets in Yemen.

In the latest exchange, the Ansarullah fired missiles at the U.S. warship USS Gravely. On Tuesday night, U.S. Central Command said its forces had shot down an antiship cruise missile.

Several shipping companies have suspended transits through the Red Sea, which is accessed from the Gulf of Aden, instead taking much longer and costlier journeys around Africa to avoid being attacked.

The Ansarullah said they will persist with their military operations until a ceasefire is agreed in the Gaza Strip and food and medicine are allowed into the territory to ease a humanitarian crisis.
