Saudi Arabian coastguard officers opened fire on an Iranian fishing boat in the Persian Gulf late on Friday, killing a fisherman, reported Iran's Borna news agency.
The incident happened after two Iranian boats fishing in the Persian Gulf strayed from their course due to big waves, reported Press TV citing the Iranian interior ministry’s director general for border affairs Majid Aqa-Babaei.
"We are pursuing this matter to determine if the Iranian boats had crossed the Saudi border or not, but the action of the Saudis does not comply with humanitarian and navigational principles," he said.
There was no immediate Saudi reaction.
