Saudi TV says missile or drone intercepted over Riyadh
Social media users posted video of what appeared to be an explosion in the air over Riyadh. Saudi state TV quoted authorities in the kingdom acknowledging the interception.
The Houthis did not immediately acknowledge launching a missile or a drone toward Riyadh.
The Houthis have held Yemen's capital, Sanaa, since September 2014. Saudi Arabia and its allies launched a war against them in March 2015 in support of Yemen's internationally recognised government.
The war has been mired in a stalemate for years. Riyadh has been targeted in sporadic missile attacks in that time, while the Houthis also have launched missile and drone strikes.
Western experts, Saudi Arabia and the US say Iran has supplied arms, including ballistic missiles to the Houthis. Iran denies that, though devices in the weapons link back to Tehran.
Yemen's war has killed tens of thousands, displaced millions and, according to the UN, left 16 million on the brink of famine.
