Saudi Arabia intercepted and destroyed a ballistic missile over Kingdom after it was launched from conflict-torn Yemen, with debris landing inside the capital's international airport.
Yemen's Shiite Houthi rebels fired the missile from Yemeni territory said they were targeting the airport, according to the Huthis' Al-Masirah television channel.
Residents in Riyadh reported a loud bang near the airport after the missile, the firing of which was claimed by Iran- backed Huthi rebels, was shot down, but authorities reported no major damage or loss of life.
The attack underscores the threat posed by the raging conflict in Yemen, increasingly spilling across the border since a Saudi-led coalition began its military intervention in 2015.
"This evening a ballistic missile was fired from Yemeni territory towards the kingdom," the Saudi Press Agency quoted coalition spokesman Turki al-Maliki.
"The missile was launched indiscriminately to target the civilian and populated areas... Shattered fragments from the intercepted missile landed in an uninhabited area of the airport and there were no injuries," he added.
Civil aviation authorities said the airport was functioning normally and that flights were operating as scheduled.
Saudi Arabia led a 2015 intervention in Yemen to prop up the government of President Abed Rabbo Mansour Hadi after the Houthi rebels forced him into exile.But two years later, the kingdom appears to be in a quagmire.
Hoping for a quick victory against what it saw as Iranian expansionism in its backyard, Riyadh has so far been unable to remove the Houthis from Yemeni capital Sanaa.
Aside from occasional missiles, Saudi territory has also been hit repeatedly by the rebels' cross-border incursions, raising fears the conflict could drag out yet further.
In July, a ballistic missile fired from Yemen was shot down close to Mecca, a month before the annual Hajj pilgrimage to Islam's holiest site. In the frontier provinces of Jizan and Najran, thousands of mortar rounds and crude rockets have hit schools, mosques, and homes.
Thousands of residents have been evacuated from border towns across the southwest to create a buffer zone.Saudi Arabia does not officially disclose military fatalities, but state media has frequently featured funeral notices for "martyred" soldiers.
United Nations-backed talks have failed to broker a political settlement to end the fighting in Yemen, which has left more than 8,600 people dead since the coalition intervened.
A cholera outbreak has claimed more than 2,100 lives in Yemen since April as hospitals struggle to secure supplies amid a coalition air and sea blockade.
The United Nations has warned that Yemen now stands on the brink of famine.
