US President Donald Trump said that in his recent phone call with Russian counterpart Vladimir Putin, he had made "no progress at all" on efforts to end the conflict in Ukraine.

Speaking to reporters, Trump stated that over their phone call he and Putin discussed a lot of things, including Iran and the Russia-Ukraine conflict.

"We had a call. It was a pretty long call. We talked about a lot of things including Iran and we also talked about, as you know, the war with Ukraine. I'm not happy about that," Trump said.

Asked whether any progress was made on potential deal to end the conflict in Ukraine , Trump responded, "No. I didn't make any progress with him today at all."

During their telephonic conversation, Putin made it clear that Russia will "not back down" on its goal of "eliminating" the root cause of the war in Ukraine, Al Jazeera reported

"Russia will not back down," Kremlin aide Yuri Ushakov told reporters after Putin's call with Trump. However, he added that Putin expressed "readiness" to "seek a political and negotiated solution to the conflict.

"Putin emphasised that Russia seeks to achieve its goals in Ukraine and remove the "root causes" of the conflict, Ushakov said. The "root cause" here refers to Ukraine's push to join NATO, following which Russia launched a full-scale invasion of Ukraine in 2022 to prevent Kyiv from joining the US-centric alliance.

The Trump-Putin phone call between two leaders came a day after the US paused promised weapon deliveries to Kyiv, including air defence missiles and precision-guided artillery, Al Jazeera reported.
