Alarm in UK and US over possible Iran-Russia nuclear deal

Britain and the US have raised fears that Russia has shared nuclear secrets with Iran in return for Tehran supplying Moscow with ballistic missiles to bomb Ukraine.

During their summit in Washington DC on Friday, Keir Starmer and US president Joe Biden acknowledged that the two countries were tightening military cooperation at a time when Iran is in the process of enriching enough uranium to complete its long-held goal to build a nuclear bomb.

Iran responded by breaching agreed limits on the quantity of enriched uranium it could hold.

Soon after Vladimir Putin launched the full-scale invasion of Ukraine, Iran began supplying Shahed delta winged drones to Moscow and helped Russia build a factory to make more to bomb targets across Ukraine. In April this year, Iran launched a Russian-style missile and drone attack aimed at Israel, though it was essentially prevented and stopped with the help of the US and UK.

Last week in London, Blinken said that US intelligence had concluded that the first batch of high-speed Iranian Fath-360 ballistic missiles, with a range of up to 75 miles (120km), had been delivered to Russia.

Able to strike already bombarded frontline Ukrainian cities, the missiles prompted a dramatic reassessment in western thinking as well as fresh economic sanctions.

The leaders and their aides discussed the war in Ukraine, the crisis in the Middle East, Iran and the emerging competition with China.
