Saudi Arabia has hit and destroyed a "ballistic missile" northeast from its capital Riyadh after it was launched from Yemen.
Saudi air defence forces were quoted by broadcaster Al-Arabiya as saying they intercepted the missile north-east of the capital.
"Travelers across King Khalid worldwide airport in Riyadh, we assure you that the movement is going on as normal and usual, and trips going according to time", the airport tweeted.
Media tied to Yemen's Houthi rebels, including al-Masira, claimed a short-range Burkan H2 missile was sacked in response to "Saudi-American aggression and crimes against the people of Yemen".
It is believed to have been fired from Yemen, where a military alliance led by Saudi Arabia has launched thousands of air strikes against the armed Houthi movement, which now controls much of the country. Riyadh is around 620 miles (1,000 kilometers) north of the border with Yemen. The attack killed 29 civilians.
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 U.S., which is one of the kingdom's most important military suppliers, has backed the coalition with logistical support. The Houthis have been targeting various Saudi cities with missiles since the beginning of the war of the Saudi-led coalition against the Houthis in Yemen in 2015.
Saudi Arabia is leading a campaign to defeat the Houthis.
