Saudi authorities said Riyadh's international airport had been targeted again, a day after 13 people were killed.
Saudi Arabia says one person has been killed and several injured in fresh strikes on Riyadh's international airport, a day after 13 people were killed and hundreds injured in a strike claimed by Yemen's Iran-aligned Houthis.
Saudi-led coalition forces in Yemen said an "unidentified projectile" had targeted Riyadh's international airport terminal four in the early hours of Monday, causing a fire.
The attack killed one person — a Pakistani resident — and wounded 11 others, Saudi Arabia's civil aviation authority said.
The coalition also said Saudi air defences had intercepted a cruise missile in the vicinity of Riyadh's King Khalid International Airport.
It later added that a drone had been intercepted and destroyed in the kingdom's Eastern Province.

The strikes have exposed vulnerabilities in Saudi defence capabilities as the kingdom wages an air campaign against the Iran-aligned Houthis, who are fighting a ground war in Yemen against the Saudi-backed Yemeni government.
The airport has been closed after an earlier attack on Sunday, although a long-planned international energy conference went ahead in Riyadh as planned.
In a televised speech, Houthi military spokesperson Yahya Saree claimed responsibility for the earlier attack and said the group had attacked the airport in Dammam in Saudi Arabia's eastern province and two facilities of Saudi oil giant Saudi Aramco 2222.SE.
The Saudi government's media office and Aramco did not respond to requests for comment.
The Saudi civil aviation authority confirmed the latest strike on Dammam's King Fahd International Airport, adding that "damage assessments and safety inspections of airport facilities are under way".
An eyewitness aboard a taxiing aircraft at the Dammam airport told Reuters that around 8:30 pm Sunday local time (4.30am AEDT Monday), they saw a projectile strike the tarmac beside several parked aircraft, causing a fire.
The witness said the aircraft returned to the gate, where passengers disembarked and were told to leave the airport.
Flight-tracking website Flightradar24 showed several delays and cancellations for arrivals and departures at Dammam airport, which serves the capital of the oil-producing region and is the kingdom’s third-largest airport.
The Houthis earlier had renewed their warning to airlines, airport workers and travellers against using Saudi airports.
"We urge everyone to take our warnings seriously, and Saudi Arabia bears responsibility for any failed interceptions," the group said.
Saudi Arabia has stepped up its military involvement in Yemen in recent weeks, launching strikes against the Houthis and backing a Yemeni government counteroffensive after the Houthis seized strategic territory along the Red Sea coast last month.
The Houthis said that Saudi Arabia carried out 124 air strikes in Yemen in the past 24 hours, including against the capital Sanaa and the group's stronghold Saada.
Yemen's Houthi-run foreign ministry said that further Saudi military action in Yemen would trigger a stronger response, adding that its actions would be guided by the principle of reciprocity.
"Unless the Saudi enemy stops its aggression and interference in Yemen, worse is yet to come, God willing," the ministry said in statements carried by Houthi-run Al Masirah television.
United States President Donald Trump said over the weekend the United States was considering joining Saudi strikes on the Houthis in the conflict, a spillover from the wider war with Iran that the US and Israel launched in February.
