Vladimir Putin

Putin said he was responding to Britain’s decision this past week to provide Ukraine with armor-piercing rounds containing depleted uranium. Russia falsely claimed these rounds have nuclear components.

Vladimir Putin's visit to Crimea Saturday marked the anniversary of the peninsula's annexation from Ukraine, a move that most of the world denounced as illegal in 2014.

A "dirty bomb" is a device that uses explosives to scatter nuclear waste.

Russia has suffered a series of setbacks nearly eight months after invading Ukraine in a campaign many thought would be short-lived.

Pope Francis uttered his strongest plea yet about the seven-month-old war in Ukraine, which he denounced as an “error and a horror.”

The U.S. Embassy in Moscow has issued another security alert for Americans in Russia, warning them to depart “immediately while limited commercial travel options remain.”

The 29-year-old was the daughter of political theorist Alexander Dugin, a prominent proponent of the “Russian world” concept and a vehement supporter of Russia's invasion of Ukraine.

“The brutal invasion (by) Russia is losing momentum. We know that with the bravery of the Ukrainian people and army, and with our help, Ukraine can win this war.”

Zelenskyy pushes for harsher sanctions as the war in Ukraine persists
