Iran's Islamic Revolutionary Guard Corps (ICRG) say they have captured a Saudi boat which allegedly "trespassed" into Iranian waters on Friday.
The boat reportedly left the Saudi port of Darin and was "intercepted at Bushehr" by the Revolutionary Guards.
Four sailors on the boat have been arrested, according to Iran's Fars News agency, and are being questioned.
Iran's interior ministry confirmed this on Friday and added that the four men arrested were Indian nationals.
