DUBAI - The Saudi navy has intercepted and destroyed a remote-controlled explosive-laden boat off the Red Sea port of Yanbu, Saudi state TV reported on Tuesday, citing the Saudi defence ministry.
Investigations are ongoing to identify those behind the attack, it added.
Vessels have previously come under attack in Red Sea waters.
In December, Saudi Arabia said that a tanker anchored at Jeddah port was hit by an explosive-laden boat. This followed a separate incident at another Saudi terminal on the Red Sea where a tanker was damaged by an explosion.
A Saudi Arabian-led military coalition engaged in Yemen has in the past foiled attempted assaults using explosive-laden boats it says are launched by Yemen's Iran-aligned Houthi movement.
