US President Donald Trump on Tuesday cautioned Russian President Vladimir Putin about the ongoing Russia-Ukraine conflict, suggesting that Putin is “playing with fire.” Trump implied that his involvement has prevented severe consequences for Russia.

Earlier, Trump expressed dissatisfaction with Putin’s actions and criticized Ukrainian President Volodymyr Zelensky for his comments about US responses to Russian attacks, New York Post reported.

In response, Dmitry Medvedev, Deputy Chairman of the Russian Security Council, cautioned that growing tensions might lead to a far more devastating battle, citing the prospect of World War III.
