Tesla CEO Elon Musk mocked Russian President Vladimir Putin for invading Ukraine on the 14th and offered a one-on-one duel.
Musk tweeted that "I'm asking Putin for a one-on-one duel" and "It's Ukraine to bet on."
He wrote Putin's name in Russian and the word Ukrainian in Ukrainian.
He then asked in Russian, "Do you agree to this fight?" to the Russian Kremlin.
"If Putin can easily humiliate the West, he will accept my challenge," he said. "But he won't."
Earlier, Musk had been supporting Ukraine since Russia's invasion of Ukraine.
At the request of Ukraine's Deputy Prime Minister and Minister of Information and Communication Mikhailo Fedorov, the satellite Internet Starlink service was also provided.
Russia, on the other hand, protested that Musk interfered with its interests.
Russia also responded to Musk's tweet asking Putin to duel.
Dmitry Rogozin, president of the Federal Space Agency, Los Cosmos, quoted a passage from a fairy tale book written by great writer Aleksandr Sergeyevich Pushkin, commenting, "Little devil, you are still a child and a weakling. Fighting with me is a waste of time."
Ukraine, on the other hand, supported Musk.
Deputy Prime Minister Fedorov wrote on Twitter: "I am confident that Musk can send Putin to Jupiter."
