Iran's Revolutionary Guards have detained a Saudi Arabian fishing boat and arrested its crew, an Iranian state news agency reported on Saturday, at a time of increased diplomatic tension between the two regional powers.

Relations between Iran and Saudi Arabia are at their worst in years, with each accusing the other of subverting regional security and supporting opposite sides in conflicts in Syria, Iraq and Yemen.

Iranian media reported last month that Saudi border guards had opened fire on Iranian fishing boats in the Gulf, killing a fisherman and arresting three others.

Iran has urged Saudi Arabia to release the trio, who Tehran said had legal documents but lost their way.

The Saudi Information Ministry said it had intercepted the boat in Saudi waters on June 16 and that three members of Iran's elite Revolutionary Guards had been detained in the incident.
