The Saudi Air Defence Force intercepted a ballistic missile fired by Iran-backed Houthi rebels towards the kingdom on Monday evening, an official said.
It was fired from Emran province in Yemen, towards civilian areas in Najran, according to spokesman for the Arab coalition, Col Turki Al Malki.
The missile was intercepted by the Saudi Air Force, with no damage reported, he said.
"Such hostile acts by the Iran-backed Houthi militias prove the continuing involvement of the Iranian regime in supporting the Houthi militias
with qualitative capabilities in a flagrant and explicit violation of UN resolutions 2216 and 2231, with the objective of threatening the security of the Kingdom of Saudi Arabia, as well as the regional and international stability," he said.
Launching ballistic missiles towards densely populated cities and villages breaches international humanitarian law, he said.
The Houthi rebels are regularly accused by Saudi Arabia of firing ballistic missiles into the kingdom. The missiles are believed to be the result of covert military support from Iran.
