Iran-backed Houthis in Yemen issued a warning after Saudi-backed anti-Houthi Yemeni forces bombed the Sana'a airport, saying, "The criminal Saudi regime...[ended] the de-escalation and ceasefire phase and [declared] the start of war." It added that the aggression will not go unanswered or unpunished, saying that the response to the strikes will be "earth-shattering" and "without delay".
