 As protests and pushback against Russia's invasion of Ukraine are picking up steam in a growing number of nations, the Daily Mail reported that images of Russian President Vladimir Putin looking like Adolf Hitler are popping up all over the place — and that even "Adolf Putin" graffiti has been scrawled on Russian buildings.

Here are a few other "Adolf Putin" examples from around the globe:

What else?

A European Union spokesman said Friday that Putin's actions are comparable to the Nazis' in World War II, the Daily Mail noted.

"He is talking about de-Nazifying Ukraine, but he behaves like Nazis," Peter Stano told reporters in Brussels, the outlet said. "So this is all in his head."

Ukraine President Volodymyr Zelenskyy appeared to blast President Joe Biden and others in an early Friday morning video, saying that Ukraine has been "left alone" to defend itself against invading Russian forces while Biden watches "from a distance."

Russian troops moved into Ukraine's capital city Kyiv on Friday, as officials urged residents to stay indoors and "prepare Molotov cocktails" to defend against the advancing enemy force, the New York Times reported.

While Ukraine claimed Putin suffered significant losses, including a missile strike at military base in Russia, other video showed a Ukrainian plane shot down over Kyiv.
