The authorities in Saudi Arabia reopened an international airport in the capital on Sunday after a spate of deadly attacks, even as the Iran-backed Houthi militia in Yemen vowed to keep striking the facility.

King Khalid International Airport in Riyadh, the capital, said on Saturday night that flights would resume on Sunday. In a statement, it advised travelers to “verify the status of their bookings and flights before heading to the airport.”

The airport had been closed to the public since Oct. 10, when a cruise missile launched by the Houthis struck a passenger terminal, killing at least 13 people and injuring more than 300. The militia, from northern Yemen, has launched at least three other deadly attacks on the airport this month, including one that hit a plane on the tarmac and killed three people.

Soon after the airport issued its statement on Saturday, a Houthi military spokesman, Yahya Saree, renewed a warning to airlines and travelers. He told them to avoid using the airport “because it is a military target” and said the Saudi government would “bear responsibility for the consequences” of reopening it.

After four years of relative peace, the Houthis and the Saudis resumed attacking each other earlier this month amid the broader U.S.-Israeli war with Iran, the Houthis’ primary backer.

The Houthis have been launching near-daily attacks on Riyadh, described those attacks as retaliation for deadly Saudi airstrikes in Yemen, including many that have killed and injured civilians.
