The US is planning to send advanced air defence systems to Ukraine after Donald Trump signed a minerals deal with Kyiv and threatened to walk away from peace talks. One Patriot system will be moved from Israel after undergoing refurbishments, while a second system could be sent by Germany or Greece, according to four officials. Mr Trump paused all military deliveries to Ukraine after a row with Volodymyr Zelensky in the Oval Office.

But he has since grown frustrated with Vladimir Putin’s refusal to commit to a ceasefire and has withdrawn from formal peace negotiations. The officials, speaking to the New York Times, refused to confirm whether the proposed shipment reflected a change in the US president’s approach toward Ukraine. Joe Biden, the former US president, secured the deal with Israel in September ahead of Mr Trump’s election win, according to a former White House official.

It comes ahead of a mooted three-day ceasefire this week while Putin’s allies are in Moscow for Victory Day. Mr Zelensky has threatened to ignore the truce after dismissing it as a “theatrical performance”. Last year, Mr Zelensky asked Western allies for at least seven Patriot defence systems to protect Ukrainian cities from Russian missile attacks.

Kyiv has eight, but only six are currently working as two are reportedly being refurbished. A spokesman for the US national security council said it did not provide details on the strength and placement of defence systems. “President Trump has been clear: he wants the war in Ukraine to end and the killing to stop,” he added.
