US President Donald Trump has warned Iran that it will face "dire" consequences if Yemen's Houthis continue to attack international shipping lanes.
He said the Iranian leadership would be held responsible for "every shot fired by the Houthis", which have long been backed by Tehran. The group later said it had targeted a US aircraft carrier three times in the past two days.
The Houthis first tried to attack the USS Harry S Truman in the Red Sea on Sunday following deadly US strikes on Yemen.
The Pentagon said it had struck 30 targets in Yemen since Saturday, in the biggest US military operation in the Middle East since Trump returned to the White House.
