On Thursday, Putin spoke for an hour in Kaliningrad to schoolchildren from all over Russia about the “Talking about what’s important” lesson that starts the school year.

A snippet from this speech has been viewed more than 100,000 times after being posted by the Financial Times’ Max Seddon.

“Putin is in Kaliningrad speaking to schoolchildren,” Seddon wrote in the caption.

“He says the Russian education minister told him that children in the Russian-occupied Donbas ‘don’t know that the bridge to Crimea exists’ and ‘didn’t even know that Ukraine and Russia were part of a united country.’”

Alongside the Moscow-approved message being spoken to the children, viewers also commented on Putin’s behavior while speaking.

The Russian president continued to slouch in his chair in an odd position, repeatedly tapping and moving his feet as he spoke.

Some social-media users insisted that Putin’s behavior did not look like natural and questioned whether a doctor would be able to deduce what could be wrong, if anything, with the Russian leader.

A Reddit post also questioned whether there were any medical explanations for Putin’s movements.

The post went up late Thursday and so far has more than 600 upvotes and over 260 comments.

Putin’s behavior on camera since the war in Ukraine began on February 24 has been regularly scrutinized as viewers question whether the leader is physically or mentally well.

Despite reports claiming that Putin has cancer, Parkinson’s disease or both, there is no evidence that he is ill and the Kremlin has repeatedly stated that the Russian leader is in good health.

The Moscow Times reported that journalist Alexei Venediktov wrote on his Telegram channel that he had asked Kremlin spokesman Dmitry Peskov about the cancer rumors.

“Fiction and untruth,” Peskov told Venediktov, which led the journalist to ask if it was correct to say that Putin does not have cancer. “Correct,” Peskov answered.

However, three U.S. intelligence leaders have told Newsweek that Putin was treated for advanced cancer in April.

These high-ranking officials, who represent three separate intelligence agencies, said they had seen a classified U.S. report on Putin confirming this.

Newsweek has contacted Russia’s Ministry of Foreign Affairs for comment.
