US special envoy Steve Witkoff will meet Russian President Vladimir Putin on Wednesday following what a US official described as “constructive” talks with Ukrainian President Volodymyr Zelenskiy in Norway, as US President Donald Trump urged Kyiv to reach a deal to end the war.

Ukraine presented new ideas and proposals during the talks in Oslo on Tuesday, which also involved Norwegian Prime Minister Jonas Gahr Store, Finnish President Alexander Stubb and European and NATO representatives. The discussions made “meaningful progress” towards a coordinated approach to engaging Russia, the US official said.

The talks covered key elements of a comprehensive peace framework, including security guarantees for Ukraine, a post-war economic plan and a broader European security architecture. Witkoff would seek to establish a path towards direct trilateral and wider multilateral negotiations, the official added.

Zelenskiy travelled to Oslo amid worsening relations with Washington as Trump has sought closer engagement with Moscow. Kyiv has complained that the US has withheld vital military support and intelligence.

Following the Oslo meeting and an earlier phone call with US Secretary of State Marco Rubio, Zelenskiy said Ukraine was once again receiving early warnings of Russian missile attacks.

“Now it works, it's great,” he said, adding that he and Rubio had discussed supplies of Patriot missile interceptors and the Starlink satellite communications system. Kyiv had previously complained that Starlink had stopped working when mounted on fast-moving objects such as drones.

Zelenskiy said he had also discussed security guarantees modelled on Article 5 of the NATO treaty, which stipulates that an attack on one member is considered an attack on all.

“I am thankful to the American side that they underlined again that it will be strong,” he said.

He reiterated Ukraine's desire for a trilateral meeting involving the leaders of Ukraine, Russia and the US to discuss key issues related to ending the war.

Store described the Oslo meeting as good and constructive, while Stubb said he believed the peace process was “back on track”.

Trump, however, on Tuesday urged Ukraine to reach a settlement, saying Moscow wanted to end the war.

“Ukraine has to want to settle this war,” he told reporters, suggesting Russia had the upper hand because “Russia is a big machine — they just keep grinding forward, and that's what they've done. They've taken a very large piece of land.”

Trump has repeatedly criticised Zelenskiy and previously called for him to be replaced. Washington has denied deliberately undermining Ukraine's war effort.

US-Russia engagement has also drawn criticism in Congress and concern among European governments, particularly after Trump lifted sanctions on Russian diesel under a deal with Putin and issued a broad waiver of tougher sanctions that were due to take effect this week.

Meanwhile, US Secretary of State Rubio acknowledged on Tuesday that a shipment of Patriot missile interceptors purchased by European countries for Ukraine might not yet have been delivered. He denied that Washington had changed its policy towards Kyiv.

“There has not been some deliberate political directive to go out and harm Ukraine,” Rubio said during a visit to India.

The Trump administration has largely stopped supplying weapons directly to Ukraine but allows European countries to purchase US weapons for Kyiv through the Prioritised Ukraine Requirements List (PURL) programme. Washington has also continued providing intelligence and technology support.

A source familiar with the matter said most weapons deliveries under the programme were continuing, but US Defence Secretary Pete Hegseth had not approved Ukraine's latest requests for Patriot interceptors.

Hegseth said US policy had not changed and stressed the need to maintain American weapons stockpiles.

“Certainly, with things like interceptors, we want to make sure our guys have the most possible as well,” he said.

He also denied that Washington had withdrawn Ukraine's access to Starlink, owned by Elon Musk's SpaceX, suggesting that the issue concerned compliance with the company's terms of service.

Musk has said Starshield, the military-grade version of Starlink, is controlled by the US government and that any restrictions on its use ultimately rest with Trump.

Meanwhile, Russia continued attacks on Ukrainian cities and energy infrastructure despite Trump's call for both sides to refrain from targeting each other's energy systems.

Russian strikes overnight hit electricity infrastructure across western Ukraine, cutting power in areas that had previously been spared. Russian forces also attacked energy facilities in seven regions, while drones struck an energy facility in Kyiv, leaving four districts without electricity, according to local authorities.

Russia's Defence Ministry said on Tuesday that its forces had struck three cargo vessels in Ukraine's port of Reni and two other cargo vessels travelling towards Odesa. It also reported attacks on two logistics hubs.

Ukraine had refrained for several days last week from striking Russian oil refineries following Trump's request but resumed the attacks after Russia showed no sign of complying, according to the report. Both sides have also targeted data centres.

The deterioration in US-Ukraine relations intensified after Trump lifted sanctions on Russian diesel in a deal with Putin, saying the move would help lower fuel prices ahead of the November 3 US midterm elections.
