Quote from CNN's article:

(CNN)Yemeni rebels on Saturday targeted an airport in Saudi Arabia's capital with a ballistic missile, according to Yemen's Houthi-controlled Defense Ministry.

But the missile was intercepted over northeast Riyadh, the Saudi Ministry of Defense said in a statement carried on government-backed Al-Arabiya television.

Yemen's Defense Ministry said the missile attack "shook the Saudi capital" and the operation was successful. The attack was conducted using a Yemeni-made, long-range missile called the Burqan 2H, it said.
