Why is Russia massing troops near Ukraine?

The security situation in eastern Ukraine is flaring up again, seven years into a simmering conflict between Moscow and Kyiv that started with Russia's annexation of Crimea in 2014. Increased numbers of Russian armed forces have been moved to the region, Ukraine says two of its servicemen were killed earlier this week, and Moscow is blaming Ukraine for the death of a five-year-old in a reported explosion in a region controlled by Russian-backed separatists. The European Union is ‘severely concerned’ about the situation and the United States has put its troops in Europe on high alert. So why is Russia massing forces near Ukraine now? Is it a test for new US President Joe Biden and – if so – could it exacerbate tensions between the old Cold War rivals? What do events tell us about the intentions of Russia’s President Putin and Ukraine’s President Zelensky? Join Ritula Shah and guests as they discuss the latest escalating tensions between Ukraine, Russia and the West.
