Yemen's Houthi rebels have claimed responsibility for an explosion in Riyadh, saying they fired a long-range ballistic missile that travelled more than 800km 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.
According to videos published on social media, smoke could be seen rising from an area near Riyadh's King Khalid International Airport.
The official Saudi news agency, SPA, quoted Colonel Turki al-Maliki as saying, that at exactly 20:07 (local time) a ballistic missile was fired from Yemeni territory towards the kingdom.
Maliki said Saudi forces used a surface-to-air Patriot missile to destroy the missile in an uninhabited area east of King Khalid International Airport.
He added that there were no reported casualties.
Al Jazeera could not independently verify the reports.
In an interview to Al Jazeera earlier this month, Mohammed Abdul Salam, a spokesman for the Houthi rebels, threatened to to escalate operations on the Yemen-Saudi border and target deep inside the kingdom.
"Abu Dhabi and others that target Yemen, are as far as we're concerned, are a fair military target. Any country that targets Yemen will be struck by our missiles."
The war in Yemen, the Arab region's poorest country, started in 2014 after Houthi rebels seized control of the capital Sanaa and began pushing south towards the country's third-biggest city, Aden.
Concerned by the rise of the Houthi rebels, 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.
