The deputy head of Iran's port authority, Jalil Eslami, said in a report by state news agency IRNA on Tuesday that Britain had shown an interest in overcoming the problem and documents had been exchanged.
Last month British marines seized an Iranian tanker, named Grace 1, off the coast of Gibraltar on suspicion it was taking 2.1 million barrels of oil to Syria - in breach of an European Union arms embargo.
The Gibraltar government does not officially confirm reports that it intends to release Iran's Grace 1 supertanker later on Tuesday, an official representative of Gibraltar told Sputnik.More news: Cincinnati Masters: Andy Murray beaten by Richard Gasquet in singles tennis return
Opposing news reports fueled confusion Tuesday over the fate of an oil tanker seized near the British territory of Gibraltar last month. He did not elaborate on the measures, but expressed hope that "the vessel would continue to operate under the flag of the Islamic Republic of Iran".
But Iran's semi-official Fars news agency quoted unidentified Gibraltar authorities as saying that it will be freed tonight.
Meanwhile, Britain said on Tuesday that investigations into the Iranian oil tanker Grace 1 were a matter for Gibraltar.More news: Jamie Chadwick celebrates inaugural W Series title win!
The tanker seizures and other suspected Iranian operations against shipping in the Persian Gulf region have inflamed a crisis between Iran and the West triggered by the Trump administration's decision to quit the multiparty nuclear deal with Iran a year ago and renew crippling economic sanctions. For this reason, Iran has taken other measures to circumvent the sanctions, which are said to include shipping oil to worldwide waters. So far only the United Kingdom has said it would join the U.S.in protecting tankers after the UK-flagged tanker Stena Impero was seized by Iran. Britain considers that action to have been illegal retaliation.
On August 6, Israeli regime's Foreign Minister Israel Katz said that they will be part of the US-led anti-Iran coalition.
The developments come against the background of tension in the Strait of Hormuz, one of the world's key maritime chokepoints. Following the resumption of U.S. oil sanctions on Iran, some Iranian officials have warned that continued oil exports to other Gulf countries would be hard if Iranian oil exports were cut.More news: Dentures got lodged in man's throat for days after surgery
