Saudi Arabia says it has shot down a long-range ballistic missile that was fired towards the capital Riyadh by Yemeni rebels.
A loud explosion was reported near Riyadh's airport as the projectile fired from neighbouring Yemen travelled more than 300 miles across the border.
Footage posted on social media shows black smoke in the sky near King Khalid International Airport.
Saudi Arabia says its defence forces intercepted a missile "of limited size" north-east of Riyadh and that it did not cause any damage or injuries.
Local media published photos of a metal part purportedly from the missile.
