UK halts all Iran flights as allies step up sanctions

Mr Blinken echoed the E3 statement, saying that the move “demonstrates how Iran’s destabilising influence stretches long beyond the Middle East”.

The Western sanctions come as Russia has continued to make gains in eastern Ukraine, with Moscow’s forces rapidly approaching the key settlement of Pokrovsk.

Pokrovsk is an essential transportation hub. If it falls, then Russian forces will cut off one of the main supply routes in the region. This will likely force Ukraine to retreat from Chasiv Yar and the front line will move closer to Kramatorsk, a major industrial city.

The Iranian short range missile deliveries will aid the Russian advance, Mr Blinken said, by allowing Moscow to use more of its existing arsenal for targets that are further from the frontline, while reserving the new missiles for closer range targets.

The top US diplomat hit out at the new Iranian government, led by President Masoud Pezeshkian, who is said to desire a less adversarial relationship with the West.

“Iran’s new president and foreign minister have repeatedly said that they want to restore engagement with Europe. They want to receive sanctions relief. Destabilising actions like these will achieve exactly the opposite,” he said.

Mr Blinken and Mr Lammy also announced a joint trip to Ukraine this week, the first joint trip in years as UK diplomats seek to frame the secretary of state’s visit as a reaffirmation of a close partnership between the two countries, often described as the “special relationship”.

Mr Blinken said one of their goals ahead of the visit was to “hear directly from the Ukrainian leadership” about their “objectives and what we can do to support those needs”.

UK Prime Minister Sir Keir Starmer has made clear the UK government will continue to back Ukraine and send £3bn in military support to the country for as long as needed.

Last week, the UK government said it was sending hundreds more short-range missiles to Ukraine in a package worth £162m.

But Ukrainian President Volodymyr Zelensky has criticised the pace of weapons deliveries, and asked for authorisation to strike targets deep inside Russia with Western-supplied missiles – a move the US has thus far resisted.

Mr Blinken would not be drawn on what their answer will be this time to President Zelensky’s longstanding plea during talks in Kyiv.
