LONDON, Aug 6 - Foreign ministers from the Group of Seven rich 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 towards Iran. There is no justification for this attack, said the statement of the current G 7 Chair, Britain.
The vessel was an Israeli-owned Tanker with heavy fuel filled, operated by Liberian-owned Zodiac Maritime.
Iran has denied any involvement in the suspected drone attack in which two crew members - a Briton and a Romanian - were killed.
However Iran has criticised Britain, the United States and others for the attack.
Iran's behaviour, alongside its support to non-state armed forces and proxy forces, threatens international peace and security, said the G7 statement.
We call on Iran to use all activities inconsistent with relevant UN Security Council resolutions and call on all parties to play a constructive role in promoting regional stability and peace.
The issue was discussed at a Friday behind-closed meetings of the United Nations Security Council, but the 15 member body is not expected to take any action.
