Zelenskyy said Tuesday that he had raised the issues with Rubio.

"I am grateful for his willingness to help and his clear position. First, it's about interceptors against ballistic missiles, which are needed to protect lives. Second, it's about early warning of Russian ballistic missile attacks, which is vital. Third, it's about the situation around Starlink/Starshield, which needs to be restored," he said in a social media post.

The growing frictions with the U.S. come as President Donald Trump ramps up pressure on Kyiv to stop hitting Russian oil refineries and to reach a peace deal with Moscow.

“Russia, frankly, has been fine on Ukraine ... They have not been doing that much,” Trump told reporters on Monday.

Trump's special envoy Steve Witkoff traveled to Norway on Tuesday for a new round of talks on ending Russia's war against Ukraine.

U.N. Human Rights Monitoring Mission in Ukraine said that 328 civilians were killed and more than 2,000 wounded across Ukraine last month, an 85% increase from September 2025. The U.N. said that the first two weeks of October were among the deadliest for civilians in years, driven by intensified missile and drone strikes.
