Iran seeks advanced Russian weaponry, causing US concern, as it accuses Iran of attacking maritime shipping routes. The US National Security Council spokesperson said Iran’s escalating military capabilities are alarming, especially as Iranian President Ebrahim Raisi met with President Vladimir Putin in Moscow. The US also accused Iran of aiding Houthi attacks on ships in the Red Sea. In response, the US imposed sanctions on individuals and entities allegedly involved in funneling funds to the Houthis. The sanctions freeze their assets in the US and prohibit transactions with them.
