Yemen fighting expands as Houthis attack Saudi airport: What to know

Saudi Arabia has vowed to “firmly” retaliate against an attack on Riyadh’s international airport, which left at least 12 people dead, with US President Donald Trump calling the attack “terrible”. The Saudi-led military coalition on Sunday blamed Yemen’s Iran-backed Houthi group for Saturday’s attack on King Khalid International Airport, describing it as a “full-fledged war crime”. The Houthis have not claimed responsibility for the latest strike. However, on Sunday, the Houthis, also known as Ansar Allah, renewed ⁠⁠⁠⁠their warning to ⁠⁠⁠⁠airlines, airport workers, and travellers against using ‌‌‌‌Saudi airports, saying the warning should be taken seriously ⁠⁠⁠⁠and that the ⁠⁠⁠⁠kingdom “bore responsibility for failed interceptions”.
