Foreign ministers from the Group of Seven wealthy economies said Iran was threatening international peace and security and that all available evidence showed it was behind an attack on the Mercer Street tanker last week.
“All available evidence clearly points to Iran. There is no justification for this attack,” said the statement, issued by current G7 chair, Britain.
The vessel was a Liberian-flagged, Japanese-owned petroleum product tanker managed by Israeli-owned Zodiac Maritime.
Two crew members – a Briton and a Romanian – were killed in the suspected drone attack.
In a separate statement, the US military said explosives experts from the Ronald Reagan aircraft carrier – which was deployed to assist the Mercer Street – concluded the drone was produced in Iran.
It said the explosives experts were able to recover several pieces of a drone, including a part of the wing and internal components which it said were nearly identical to previously-collected samples of Iranian attack drones.
The US military also suggested the attack may have been launched from the Iranian coast, saying the distance to the locations of the attacks “was within the range of documented Iranian one-way attack” drones.
“Some of the material was transferred to US Fifth Fleet headquarters in Manama, Bahrain and subsequently to a US national laboratory for further testing and verification,” Central Command, which oversees US forces in the region, said in the statement.
Despite Tehran’s denials, Britain, the US and others have criticised Iran for the attack.
“Iran’s behaviour, alongside its support to proxy forces and non-state armed actors, threatens international peace and security,” the G7 statement said.
“We call on Iran to stop all activities inconsistent with relevant UN Security Council resolutions, and call on all parties to play a constructive role in fostering regional stability and peace.”
Britain raised the issue at a closed-door meeting of the United Nations Security Council yesterday. No action is expected to be taken by the 15-member body.
“Iran was responsible for this attack. We know it was deliberate and targeted. There is no justification for what happened – a state sanctioned attack on a civilian vessel, passing peacefully through international waters,” Britain’s UN Ambassador Barbara Woodward said after the meeting.
