The United Kingdom has warned that Moscow is to provide Tehran with some advanced military technology that will put the security of the Middle East and world in danger.

Britain’s Defense Secretary Ben Wallace told parliament Tuesday that in return for Iranian drones it uses in attacks on Ukraine, Russia will supply the military components to the Islamic Republic.

Wallace told the parliamentarians that Iran should be held accountable for supporting Russia in war on Ukraine.

“We must hold their enablers to account,” he noted. “Iran has become one of Russia’s top military backers. In return for having supplied more than 300 kamikaze drones, Russia intends to provide it with advanced military components, undermining both Middle East and international security. We must expose this deal.”

However, Wallace did not reveal more details about the technology that Tehran is going to receive.

Reuters says the Russian Defense Ministry and Iran’s foreign ministry have refused to give a comment regarding Wallace’s statements.

Earlier, Washington said Moscow was moving to provide Tehran with advanced military assistance including air defense systems, choppers, and fighter jets.

Russia was offering the Islamic Republic “an unprecedented level of military and technical support that is transforming their relationship into a full-fledged defense partnership,” said White House National Security Council spokesman John Kirby on December 9.

The Biden administration recently unveiled sanctions against Iranian firms and entities involved in the transfer of drones to Russia for use in Ukraine.
