Eight years since the Russian annexation of Crimea, Ukraine is facing another threat from its eastern neighbour. Russia has amassed an estimated 130,000 troops and military equipment along its borders in recent weeks.
Ukraine is literally surrounded by Russian troops: along its northern border with Belarus, in Russian-occupied eastern Ukraine (Donetsk and Luhansk), in Crimea to the south, and in Transnistria, the Russian-occupied part of Moldova to the west.
