Austrian Chancellor Karl Nehammer flew to Moscow on Monday and met with Russian President Vladimir Putin to talk and discuss the ongoing war in Ukraine. Nehammer reportedly confronted Putin about Russia’s alleged war crimes and called to end the war.

“This is not a friendly visit. I have just come from Ukraine and have seen with my own eyes the immeasurable suffering caused by the Russian war of aggression,” Nehammer was quoted saying.

“I mentioned the serious war crimes in Bucha and other locations and stressed that all those responsible have to be brought to justice,” he added.

The Austrian Chancellor is the first European leader to visit Putin after the latter began the invasion of Ukraine in February. His meeting with the Russian leader drew mixed opinions among the European Union, with some casting doubt on the effectiveness of having talks with Putin.
