The airport in the Saudi capital was attacked again on Saturday and was evacuated, two regional officials said, two days after three Saudi citizens, including a pilot, were killed there as the kingdom faces an extraordinary series of assaults on the new front in the Iran war.
One official said air traffic to the Riyadh airport had stopped. The officials spoke on condition of anonymity because they weren't authorized to speak to the media.
King Khalid International Airport has been targeted multiple times in the week since a Saudi-led coalition launched a major military offensive against Iran-backed Houthi rebels in neighboring Yemen. The Houthis claimed responsibility for the earlier attacks, including one Wednesday that killed a Sudanese national.
The Houthis made no immediate statement Saturday. The Saudi government-run Center for International Communication, which oversees foreign media in the kingdom, didn't immediately respond to a request for comment.
A Riyadh resident, Ahmed Sayed, told The Associated Press he heard at least two loud explosions that rocked the capital.
