US and Ukrainian leaders discuss defence capabilities on call after Trump ‘disappointed’ by conversation with Russia’s Putin.

Ukrainian President Volodymyr Zelenskyy says he agreed with his US counterpart, Donald Trump, to work to strengthen Ukraine’s air defences, as concerns mounted in Kyiv over US military aid deliveries.

The two leaders had a “very important and fruitful conversation” by phone on Friday, Zelenskyy said.

“We spoke about opportunities in air defence and agreed that we will work together to strengthen protection of our skies,” he added in a post on the social media platform X.

The president added that he discussed joint defence production, as well as joint purchases and investments, with the US leader.

Meanwhile, US publication Axios, citing an unidentified Ukrainian official and a source with knowledge of the call, said Trump told Zelenskyy he wants to help Ukraine with air defence after escalating attacks from Russia.

This comes a day after the US president spoke to Russia’s Vladimir Putin, in a conversation he said was disappointing.

“I’m very disappointed with the conversation I had today with President Putin, because I don’t think he’s there, and I’m very disappointed,” Trump said after the call on Thursday. “I’m just saying I don’t think he’s looking to stop, and that’s too bad.”

Trump said the call with Putin resulted in no progress at all on efforts to end the war, and the Kremlin reiterated that Moscow would keep pushing to solve the conflict’s “root causes”.

Massive drone attack

Hours after the Trump-Putin call on Thursday, Russia pummelled Kyiv with the largest drone attack of the war, killing one person, injuring at least 23 and damaging buildings across the capital.

Air raid sirens, the whine of kamikaze drones and booming detonations reverberated from early evening until dawn as Russia launched what Ukraine’s Air Force said was a total of 539 drones and 11 missiles.

Zelenskyy called the attack “deliberately massive and cynical”.

Ukraine has been asking Washington to sell it more Patriot missiles and systems that it sees as key to defending its cities from intensifying Russian air strikes.

A decision by Washington to halt some shipments of weapons to Ukraine prompted warnings by Kyiv that the move would weaken its ability to defend against Russia’s air strikes and battlefield advances. Germany said it is in talks on buying Patriot air defence systems to bridge the gap.

Trump spoke with German Chancellor Friedrich Merz on Thursday, according to Spiegel magazine, citing government sources. The two leaders discussed the situation in Ukraine, including strengthening its air defence, as well as trade issues, Spiegel reported on Friday.

In Zelenskyy’s post on X on Friday after his call with Trump, he said the two had “a detailed conversation about defense industry capabilities and joint production. We are ready for direct projects with the United States and believe this is critically important for security, especially when it comes to drones and related technologies.”

Zelenskyy also said Ukrainians are “grateful for all the support provided”, as it helps protect lives and safeguard their independence.

“We support all efforts to stop the killings and restore just, lasting, and dignified peace. A noble agreement for peace is needed,” he said.
