TEHRAN (Dispatches) – The Islamic Revolution Guards Corps (IRGC) has detained a Saudi Arabian fishing boat and arrested its crew for trespassing, the IRNA news agency reported on Saturday.
Five Indian nationals on the vessel were detained on Friday after they crossed into Iranian territorial waters in the Persian Gulf, Ardeshir Yarahmadi, a spokesman for the fisheries department of Bushehr province, was quoted as saying.
Yarahmadi said it was the second time in the past month that a Saudi boat and its crew had been detained.
On July 7, the IRGC navy seized a trespassing Saudi vessel, which had set off from the Saudi port of Dareen, in the waters off Bushehr Province.
Relations between Iran and Saudi Arabia are at their worst in years. Riyadh, along with other Arab governments, has severed ties with Qatar, citing its support of Iran as one of the main reasons for the move.
Iran has blamed Saudi Arabia for being behind deadly twin terrorist attacks on June 7 in Tehran claimed by Daesh. At least 18 people were marytred and more than 40 wounded in the attacks.
Iranian media reported last month that Saudi border guards had opened fire on Iranian fishing boats in the Persian 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 IRGC members had been detained in the incident, drawing derision from Iranian media who later interviewed the son of the fisherman killed in the incident, hailing from a poor family in Bushehr.
The kingdom’s bizarre claims went as far as to say that the seized vessel was carrying explosives and those captured intended to conduct a "terrorist act" in Saudi territorial waters.  
Relations between Iran and Saudi Arabia worsened after a deadly human crush during Hajj rituals in Mina, near Mecca, in September 2015.
Iranian officials blamed the incompetence of Saudi officials for the incident, which, according to Iran, killed 4,700 people, including 465 Iranian nationals.
