The Houthis renewed their warning on Sunday to airlines, workers and travelers not to use airports in Saudi Arabia and said the warning should be taken seriously, after the attack on Riyadh's international airport.

According to the Houthis, cited by The Jerusalem Post, Saturday's attack left 12 dead and more than 300 wounded. Saudi civil aviation extended the closure of King Khalid airport until 21:00 GMT on Sunday, under a Notice to Air Missions (NOTAM). India condemned the attack, cited the 12 dead and more than 300 wounded and called attacks on civilians completely unacceptable.
