Elon Musk, the inventor of Tesla, has become increasingly significant in discussions about the Ukraine conflict, amid new accusations that he has communicated with Vladimir Putin.
He drew severe criticism after proposing a peace plan in which Ukraine ceded Crimea to Russia.
His latest intervention involves a somewhat bizarre Twitter exchange with former Russian prime minister, senior Kremlin official, and prominent Putin ally Dmitry Medvedev.
Musk had complimented Mr Medvedev on a “pretty good troll” after he ridiculed outgoing prime minister Liz Truss.
He then asked the deputy chairman of the Security Council of Russia about it the current situation in Bakhmut, which has faced intense Russian shelling over recent days.
Mr Medvedev concluded (for now at least) the seemingly friendly discussion by suggesting he would see Musk “in Moscow on the Victory Day”.
