WASHINGTON — Secretary of State Antony Blinken signaled the U.S. would hold talks on Ukraine’s use of Western long-range weapons against Russia, after confirming Moscow had received shipments of ballistic missiles from Iran.“We’re going to look and to listen” to Ukraine’s request to lift restrictions on its use of long-range missiles, Blinken said Tuesday at a press conference with UK Foreign Secretary David Lammy in London, signaling the U.S. is open to altering its position.The two diplomats will travel to Kyiv on Wednesday, before UK Prime Minister Keir Starmer meets U.S. President Joe Biden in Washington on Friday, when Blinken said the missile issue will also be discussed.The U.S. currently opposes Ukraine using the weapons inside Russian territory, previously citing concerns about possible Russian escalation in response.Blinken said Iran had transferred a shipment of its Fath-360 missiles to Russia, defying months of warnings from the U.S. and its allies not to do so.

The joint visit with Lammy comes after Ukraine’s invasion of Russia’s Kursk region, which has left allies and partners both impressed and worried about the long-term tactical and strategic implications.The UK has previously indicated it is open to Ukraine striking military ...
