The US on Monday warned of the deepening alliance between Russia and Iran in the war in <a href="https://www.thenationalnews.com/tags/ukraine" target="_blank">Ukraine</a>, and said it would sanction anyone helping Tehran ship drones to Moscow. <a href="https://www.thenationalnews.com/world/europe/2022/10/17/kyiv-hit-by-kamikaze-drones-in-renewed-russian-attacks/" target="_blank">Russian forces attacked Kyiv </a>on Monday, using what observers say were Iranian-made kamikaze drones designed to wreak havoc on the Ukrainian capital. Vedant Patel, deputy spokesman at the State Department, said that Russia and <a href="https://www.thenationalnews.com/tags/iran/" target="_blank">Iran</a> working together in Ukraine poses a “profound threat”. “<a href="https://www.thenationalnews.com/tags/russia/" target="_blank">Russia</a> deepening an alliance with Iran is something the whole world … should be [seeing] as a profound threat and something that any country should pay very close attention to,” he said. Mr Patel said there is “extensive proof” that <a href="https://www.thenationalnews.com/world/uk-news/2022/10/17/eu-gathers-evidence-of-russias-alleged-use-of-iranian-drones-in-ukraine/" target="_blank">Russia is using Iranian drones</a> against both military and civilian targets in Ukraine. He warned companies and individuals against potentially contributing to Iran’s efforts to supply Russia with missiles and unmanned aerial vehicles (UAVs). “Anyone doing business with Iran that could have any link to UAVs or ballistic missile developments, or the flow of arms from Iran to Russia, should be very careful and do their due diligence,” Mr Patel said. “The US will not hesitate to use sanctions or take actions against perpetrators.” Nearly <a href="//thenationalnews.com/world/2022/02/24/has-russia-invaded-ukraine-what-does-moscow-want/" target="_blank">eight months since its invasion</a>, Russia has failed to gain air superiority in Ukraine, as Ukrainian forces continue to bring down Russian aircraft thanks to weapons support from allied western countries.
