Houthi military spokesman Yahya Saree: Saudi Arabia carried out 54 airstrikes across Yemen in the past 24 hours, flown by Typhoon and F-15 aircraft operating out of the Khamis Mushait and Taif bases.

In a separate message, Saree claimed the Houthis launched surface-to-air missiles at Saudi warplanes over Saada province in northern Yemen, the group's stronghold, forcing them to turn back.

Saree warned the "aggression will not pass quietly."
