Ukrainian President Volodymyr Zelenskyy says the Russian invasion could lead to the start of World War III

There is a chance that the start of World War III could be caused by the invasion of Ukraine by Russia.

Nobody knows if it started. If Ukraine falls, what is the possibility of a war? Zelenskyy told Holt that it was hard to say when the second World War started.

On February 24, Putin launched a special military operation in Ukraine, prompting global concern that the violence in Europe would lead to a third World War.

If the US does not get involved in the war on Ukraine, it could lead to World War III, as argued by former President Donald Trump.

A 36-year-old Ukrainian medic named Mila Makarova told Insider's Julia Beil and Nathan Rennolds that she didn't understand what the sudden concern was over World War III was about. She argued that the war is not new for Ukrainians.

Zelenskyy said in an NBC interview that the whole civilization is at stake because of the Russian invasion.

Zelensky said that smaller neighboring countries are watching very attentively to respond to the invasion.

According to the Office of the UN High Commissioner for Human Rights, at least 726 Ukrainians were killed and over 1,200 were injured in the Russian attack.
