The United States and the United Kingdom have joined Israel in accusing Iran of orchestrating Thursday's attack on an Israeli tanker off the coast of Oman,�despite Tehran�s firm denial.

�Upon review of the available information, we are confident that Iran conducted this attack, which killed two innocent people, using one-way explosive UAVs,� US Secretary of State Antony Blinken said in a statement Sunday.
Blinken said they are �working with partners� on what he termed an �appropriate response� to the attack.�
Earlier British Foreign Secretary Dominic Raab said the �unlawful and callous� attack had highly likely been carried out by Iran using one or more drones.
�We believe this attack was deliberate, targeted, and a clear violation of international law by Iran,� he said, adding that London was working with partners on a �concrete response.�
