A senior American official told Al Jazeera that the U.S. is providing Saudi Arabia with support to counter Houthi attacks. He claimed: "Saudi Arabia is using U.S. refueling capabilities to defend its airspace and assist forces opposing the Houthis. About 200 American advisers are providing consultation at planning centers in Saudi Arabia." The official clarified that the U.S. is not involved in the war in Yemen and added: "We are tightening the siege on Iran, which is suffering economically and feels our pressure, which will continue."
