Russian President Vladimir Putin said he would speak with US President Donald Trump later on Thursday, Interfax news agency reported.
Trump confirmed the meeting in a Truth Social post, writing, "Will be speaking to President Putin of Russia at 10:00 A.M. Thank you!"
Putin told Russian TASS state media, "Today, I will be speaking with the President of the United States, and I will definitely suggest that he use this material to promote it in the American market," he said.
It will be the sixth publicly known conversation between the two leaders since Trump returned to the White House in January and comes amid so far unsuccessful US efforts to broker a ceasefire in Ukraine.
Trump expected to speak with Zelensky
Ukrainian President Volodymyr Zelensky said on Thursday that he hopes to speak with his US counterpart, Donald Trump, on Friday or in the coming days about the supply of US weapons to Ukraine.
Speaking to reporters in Denmark, Zelensky added that Kyiv was ready to take part in a meeting of leaders to end his country's war with Russia.
The timing of that call could change, the FT added, citing people familiar with the planning.
The White House did not respond to a Reuters request for comment on the reported Zelenskiy call.
The US has paused some shipments of critical weapons to Ukraine due to low stockpiles, sources earlier told Reuters.
That decision led to Ukraine calling in the acting US envoy to Kyiv on Wednesday to underline the importance of military aid from Washington continuing, and caution that the move would weaken Ukraine's ability to defend against intensifying Russian airstrikes and battlefield advances.
The Pentagon's move led in part to a cut in deliveries of Patriot air defense missiles that Ukraine relies on to destroy fast-moving ballistic missiles, Reuters reported on Wednesday.
Putin condemned Israel's strikes on Iran
Putin previously spoke on the phone with Trump in June in a 50-minute conversation, where he said he felt the conflict between Israel and Iran needed to end, The Jerusalem Post previously reported.
According to the Kremlin, Putin had condemned the Israeli military operation against Iran and expressed concern about the risks of escalation.
"Vladimir Putin condemned Israel's military operation against Iran and expressed serious concern about a possible escalation of the conflict, which would have unpredictable consequences for the entire situation in the Middle East," Kremlin aide Yuri Ushakov told reporters.
