Escalating Tensions: Latest Developments in Russia-Ukraine Conflict.

Russian President Vladimir Putin met with China's Defense Minister Li Shangfu on Sunday, hailing the deepening military cooperation between Moscow and Beijing. Meanwhile, there has been an international outcry after Kremlin critic Vladimir Kara-Murza was jailed for 25 years by a Moscow court on Monday for treason and other offenses he denied. The U.S., U.K. and Germany condemned the sentence, with London calling it "politically motivated." Mine-clearing in Ukraine could take at least a decade, according to Britain's Ministry of Defense. Dozens of Ukrainian prisoners of war have been released as part of a major Easter exchange with Russia.
