U.S. President Donald Trump, speaking to Russian leader Vladimir Putin by telephone for nearly 90 minutes, offered to help find a solution to the Ukraine war, Kremlin aide Yuri Ushakov said in comments made public early on Sunday.

Mr. Ushakov said Mr. Trump made the offer during the call on Saturday, U.S. Independence Day, in the context of his participation next week at the NATO summit in Turkey.

Ukrainian President Volodymyr Zelensky said he also spoke to Mr. Trump.

“The American President once again confirmed his readiness to work toward a rapid end to the fighting and find solutions to overcome the crisis,” Mr. Ushakov said of Mr. Trump’s call with the Russian president.

Mr. Ushakov, who described the conversation as “business-like and quite constructive,” said Russia sought “a political-diplomatic resolution of the conflict, with due account of Russia’s fundamental approach.”

Mr. Ushakov accused Kyiv and its European allies of “counting on extending and even escalating the conflict, and on terrorism against civilians.”

He was referring to Ukraine’s long-range strikes on Russian targets, mainly linked to the oil industry, which have triggered fuel shortages in several Russian regions.

Mr. Ushakov said Mr. Putin “depicted the real situation on the battlefield where the Russian armed forces are confidently advancing, liberating one locality after another.”

Russian commanders told Mr. Putin on Friday that Moscow’s troops had captured the strategically important city of Kostiantynivka in eastern Ukraine’s Donetsk region. On Saturday, Mr. Zelensky and Ukraine’s General Staff dismissed that claim, saying Kyiv’s forces still controlled the city.

Russia has said any solution must include Moscow assuming full control over Ukraine’s Donbas region.

Ukraine rejects that assertion and Mr. Zelensky urged Mr. Putin last month to hold a one-on-one meeting with him, but the Kremlin leader refused.

Mr. Ushakov quoted Mr. Trump as saying that Washington’s envoys, Steve Witkoff and Jared Kushner, would keep trying to broker a settlement and were prepared to make another visit to Moscow. U.S. diplomatic efforts have virtually stalled as Washington is focused on the war with Iran.

Mr. Ushakov said Mr. Putin expressed hope during the conversation that U.S. diplomatic efforts in the Iran conflict would “allow for mutually acceptable long-term solutions to be found on key issues of a settlement.”

Mr. Ushakov said Mr. Putin also reminded Mr. Trump that he had an open invitation to visit Moscow.

Mr. Zelensky, writing on his Telegram account, described his conversation with the U.S. president as “very good,” including a discussion on the war’s 1,200-km front line.

“There is a real prospect to end this war and American resolve will have a crucial meaning,” he said. Mr. Zelensky said he and Mr. Trump agreed to continue discussions at the NATO meeting.
