Iran has finalised a deal to buy Sukhoi Su-35 fighter jets from Russia, with the deepening of defence cooperation between the two countries. However, there was no immediate confirmation of the deal from Russia. Russia announced it was ready to sell them after the expiry in October 2020 of restrictions on Iran purchasing conventional weapons under UN Resolution 2231.
Kyiv has accused Tehran of supplying Moscow
with Shahed-136 kamikaze drones used in attacks on civilian targets since Russia's invasion of Ukraine in February last year while Iran denies the allegation.
The United States has also expressed alarm over the growing military cooperation between Iran and Russia, with Pentagon spokesman John Kirby warning in December that Russia looked likely to sell Iran its fighter jets.
