Biden delivers 'private message to Iran' about Houthis

US President Joe Biden said he delivered a private message to Iran about the Houthi movement. 

Speaking to reporters at the White House on Saturday, Biden said: "We delivered it privately, and we're confident we're well prepared."

The statement came after US and UK forces launched air strikes on Houthi-controlled areas in southern Yemen on Saturday and Friday. 

However, the White House has said it is not "interested in a war with Yemen". 

"Everything the president has been doing has been trying to prevent any escalation of conflict, including the strikes last night," White House spokesperson John Kirby said on Friday.
