The Israel Defense Forces (IDF) said the airport was used by the Houthi rebels “to smuggle Iranian weapons into the region”, which they used to attack Israel, and to host “senior Iranian officials”.
“This is another example of the Houthis using civilian infrastructure for military purposes,” the report added.
The Houthi-run Saba news agency said three people were killed at the airport and 30 others were wounded.
It said three more people were killed and 10 wounded in other strikes on power plants and a port in the region.
It is not yet clear whether the dead were civilians or Houthi rebels.
The Iran-backed group called the attacks “barbaric” and “aggressive”. He vowed to continue striking Israel until the conflict in the Gaza Strip ends.
The Houthi rebels have been attacking Israel since the first months of the war, which began in October 2023, when Palestinian militants launched a surprise attack on Israel, killing around 1,200 people.
Israel launched repeated strikes in response to Houthi attacks.
On Saturday, the Houthis said they had struck the Nevatim airbase in central Israel. The IDF said the missile from Yemen was intercepted by the air force before crossing Israeli airspace.
The Houthis are an armed political and religious group supported by Iran. The group has ruled much of western Yemen, including the capital Sanaa, since ousting the internationally recognized government in 2015.
