Following our own assessment the UK concludes that:
It is almost certain that a branch of the Iranian military – the Islamic Revolutionary Guard Corps – attacked the two tankers on 13 June. No other state or non-state actor could plausibly have been responsible.
There is recent precedent for attacks by Iran against oil tankers. The Emirati-led investigation of the 12 May attack on four oil tankers near the port of Fujairah concluded that it was conducted by a sophisticated state actor. We are confident that Iran bears responsibility for that attack.
The Foreign Secretary said:
I condemn yesterday’s attacks on two vessels in the Gulf of Oman. Our own assessment leads us to conclude that responsibility for the attacks almost certainly lies with Iran. These latest attacks build on a pattern of destabilising Iranian behaviour and pose a serious danger to the region.
In targeting civilian shipping, international norms have been violated. It is essential that tankers and crews are able to pass through international waters safely. We call on Iran urgently to cease all forms of destabilising activity. The UK remains in close coordination with international partners to find diplomatic solutions to de-escalate tensions.
