It was the latest in a series of such attacks.

"Saudi air defences intercepted a ballistic missile launched by the Huthi militias targeting Jizan," the coalition said in a statement.

The Huthis, in a statement on their news outlet Al-Masirah, claimed that they fired a "Badr 1" ballistic missile and said it struck Jizan Regional Airport.

AFP was unable to reach the airport for comment, but open-source flight information appeared to show flights arriving and departing on time.

Saudi Arabia has since March 2015 led a coalition of Arab states fighting to roll back the Huthi rebels in Yemen and restore its neighbour's internationally-recognised government to power.

Nearly 10,000 people have since been killed in the conflict, in what the United Nations has called the world's worst humanitarian crisis.

In March, an Egyptian labourer became the first known fatality in a rebel missile attack on the Saudi capital.

Saudi Arabia accuses its rival Iran of smuggling missiles to the Huthis -- a charge Tehran denies.
