The two presidents have shared "heartfelt words" through their aides, a senior official has told Russian media

Russian President Vladimir Putin and US President Donald Trump have congratulated each other on Victory Day, an aide to the Russian president, Yury Ushakov, told journalists on Friday. The two leaders extended the greetings through aides, according to the official.

The presidents shared "heartfelt words, mutual greetings on a common holiday, great holiday," Ushakov told the Russian Channel 1 broadcaster. Washington has not officially commented on the matter.

On Friday, Russia celebrated the 80th anniversary of the Soviet triumph in the World War II against Nazi Germany. The day was packed with military parades and other ceremonial events across the nation that paid tribute to the valor and sacrifice of the Soviet people during the war.

The celebrations in Moscow, including the military parade on Red Square, were attended by upwards of 30 foreign leaders, including those of China, Brazil, Egypt, Slovakia, Serbia, and Uzbekistan. US Ambassador to Moscow Lynne Tracy skipped the event despite receiving an invitation, according to TASS.

The Moscow parade was still attended by several US WWII veterans, who were invited alongside other foreign veterans, including from Mongolia, Israel and Armenia.

On Thursday, Trump issued a public statement on the 'Victory Day for World War II'. He described the victory over Nazism as "the Allied Powers' triumph," highlighting the role of the US and never mentioning the Soviet Union. 

Earlier this month, similar statements by the US president drew criticism from Moscow. On Friday, during his speech at the annual military parade in Moscow, Putin stressed that Russia remembers the lessons of World War II and "will never accept the distortion of its events."

Since returning to office in January, Trump has pushed both Moscow and Kiev toward a truce in the ongoing conflict between the two nations but has recently voiced frustration over the lack of progress.

On Thursday, he called for a month-long "unconditional ceasefire" amid a 72-hour Victory Day truce unilaterally declared by Russia. He expressed his hope that "an acceptable ceasefire will be observed" but warned that both sides would be held accountable if a ceasefire is reached but not respected.
