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.

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

"Imagine how many Russian forces are there. But at the same time, they have not achieved the planned result," Zelensky told reporters on Oct. 27.

The crucial supply and transport hub in Pokrovsk serves as a lifeline for delivering supplies and reinforcements to the eastern front, and capturing it would bring Moscow closer to taking full control

The question of whether Ukraine should fight against or negotiate with an aggressor has been there since Russia annexed Crimea in 2014. But more than three years after it launched its full-scale invasion, the war is entering a new phase, and that word has re-entered the global debate.

Ukraine's military reportedly struck an oil refinery as well as a chemical plant in Russia's western regions overnight on Oct. 29, Russian Telegram media channels reported.

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."

Ukrainian President Volodymyr Zelensky said Kyiv is working with its partners in the "Coalition of the Willing" to draw up a peace plan, including a ceasefire, to end the Russian war against Ukraine in a similar vein to U.S. President Donald Trump's 20-point framework for Gaza.

Ukraine’s capital, Kyiv, endured two consecutive nights of Russian strikes this weekend. The latest overnight attack on Oct. 26 saw drones and ballistic missiles raining down on the city. In total, five people were killed, and more than fifty others were injured.
