Saudi Arabia has intercepted a ballistic missile from Yemen, reports say, after a loud explosion was heard near Riyadh airport.
Saudi air defence forces were quoted by broadcaster Al-Arabiya as saying they intercepted the missile north-east of the capital.
A TV channel linked to Houthi rebels in Yemen said the missile was launched at the airport.
Saudi forces have reported shooting down Houthi missiles before.
State news channel Al-Ekhbariya said the missile was “of limited size” and no damage was caused.
A long-range ballistic missile was fired at King Khalid International Airport in Riyadh, the Houthi TV channel Al-Masirah reported.
Yemen has been devastated by a war between forces loyal to the internationally-recognised government of President Abdrabbuh Mansour Hadi and those allied to the Houthi rebel movement.
Saudi Arabia is leading a campaign to defeat the Houthis.
Meanwhile, Yemen’s Houthi rebels have claimed responsibility for an explosion in Riyadh, saying they fired a long-range ballistic missile that travelled more than 500km over the border with Saudi Arabia.
A spokesman for the rebels told Al Jazeera they launched a Burkan 2-H missile towards Riyadh late on Saturday, a scud-type missile with a range of more than 800km.
“The capital cities of countries that continually shell us, targeting innocent civilians, will not be spared from our missiles,” the spokesman said.
Al Masirah, a TV network run by the Houthi rebels, also claimed responsibility for the attack on their social media account.
The war in Yemen, the Arab region’s poorest country, started in 2014 after Houthi fighters seized control of Sanaa and began pushing south towards the country’s third-biggest city, Aden.
Concerned by the rise of the Houthis, believed to be backed by regional rival Iran, Saudi Arabia and a coalition of Sunni Arab states launched an intervention in 2015 in the form of a massive air campaign aimed at reinstalling President Abd-Rabbu Mansour Hadi’s government.
Since then, more than 10,000 people have been killed and at least 40,000 wounded, mostly from Saudi-led air strikes.
