Russian President Vladimir Putin is now believed to be more dug in than ever, according to a recent intelligence assessment.

By holding nuclear drills and boasting about the successful test of a pioneering nuclear-powered cruise missile, Russian President Vladimir Putin is sending a message to President Donald Trump: Moscow wouldn’t be cowed into concessions on Ukraine.

As Trump's plan to meet Putin is called off, Zelenskyy says another bloody night in Ukraine shows Russia isn't feeling "enough pressure for dragging out the war."

European leaders vowed to work in coordination to ratchet up the pressure on Russia as the so-called “coalition of the willing” met in London to discuss strategies to end the war in Ukraine.

In addition to the economic warfare, Ukraine’s long-range strikes on refineries had by last month destroyed or damaged about 20 percent of Russia’s refining capacity, according to one analyst. That has caused severe gasoline shortages in several regions, as Ukraine tries to bring the pain of war to ordinary Russians.

As Zelenskyy lauds Europe and the U.S. for ramping up economic pressure on Putin over the war in Ukraine, Moscow dismisses them as a counterproductive "act of war."

An estimated 2,000 Colombian mercenaries serve on Ukraine's front lines, defending against Russia's aggression. They face death and serious injuries on the conflict's brutal battlefields, for pay that could change their lives on the return home.

European leaders want to build on President Trump’s sanctions on Russia with new commitments of financial and military support for Kyiv.
