A Saudi news agency confirms one of two vessels ablaze after an assault while sailing in the Red Sea; US military says latest strikes "further degrade Iran’s ability to attack commercial vessels".

US completes 10th consecutive night of strikes as tankers are targeted in the Strait of Hormuz and Yemeni rebels threaten broader war.

This comes as the Houthis, an Iranian-backed faction in Yemen, announced a maritime blockade on Saudi Arabian ships and threatened to open a new front in the war.
