who is russia at war with

As of my last knowledge update in October 2023, Russia has been engaged in an ongoing conflict with Ukraine, which escalated significantly in February 2022 when Russia launched a large-scale invasion of Ukraine. The conflict has roots in earlier tensions, notably the annexation of Crimea by Russia in 2014 and ongoing support for separatist movements in Eastern Ukraine. The situation is complex and dynamic, so for the most current information, I recommend checking the latest news sources.
