The US state department has confirmed it offered millions of dollars to the captain of an Iranian oil tanker which is at the centre of a diplomatic row.
Brian Hook, head of the department’s Iran Action Group, emailed the captain of the Adrian Darya 1 about sailing it somewhere the US could seize it.
The vessel was suspected of moving oil to Syria, and was temporarily impounded by UK authorities in Gibraltar in July.
It was released last month after Iran gave assurances about its destination.
The US justice department, which had tried to block the release, then issued a warrant to seize the tanker.

Reports of the cash offer first appeared in the Financial Times on Wednesday and have been confirmed by the state department.
“We have conducted extensive outreach to several ship captains as well as shipping companies,” a spokeswoman told AFP news agency.
The US blacklisted the tanker last Friday. A Treasury Department statement said the vessel was being used to transport 2.1 million barrels of Iranian crude oil for the benefit of Iran’s Revolutionary Guard – a branch of the country’s armed forces the US has designated a terrorist organisation.
What did the emails say?
According to the Financial Times, Mr Hook sent an email to the Indian captain of the Adrian Darya 1, Akhilesh Kumar, before it imposed sanctions on the ship.
“I am writing with good news,” the email read. The Trump administration was willing to pay the captain several million dollars to take the ship somewhere it could be seized by US authorities.
The emails reportedly carried a state department phone number to make sure the captain – who took over the ship after it was impounded – did not think they were fake.
Mr Hook told the newspaper that the state department was “working very closely with the maritime community to disrupt and deter illicit oil exports”.
Mr Kumar ignored the emails. The US then imposed sanctions on him personally when they blacklisted the Adrian Darya 1.
On Twitter, Iran’s foreign minister Javad Zarif accused the US of “outright bribery”.
The Trump administration announced on Wednesday new sanctions on an Iranian shipping network used to sell oil, and offered $15m to anyone who can help to disrupt the system.
What is the tanker row?
The Adrian Darya 1, previously known as Grace 1, was detained by British authorities in Gibraltar on 4 July after it was suspected of moving oil to Syria in breach of EU sanctions.
It was released on 15 August after Iran gave assurances it would not discharge its cargo in Syria – despite the last-minute US effort to prevent its release.
Tracking websites indicate the ship is currently in the eastern Mediterranean, although it has reportedly turned off its signalling device.
Its initial seizure sparked a diplomatic crisis between the UK and Iran, which saw Iran seize a British-flagged and Swedish-owned oil tanker, the Stena Impero, in the Gulf.
On Wednesday, Iran said it would free seven of the Stena Impero’s 23 crew members on humanitarian grounds.
