Bessarabia is a historical region, a former puffer zone of the Russian, Austrian and Ottoman empires. It’s boundaries lay mainly in today’s Moldavia (including Transnistria) and to a smaller part in the south of Ukraine (see Wikipedia). There are attempts to revitalize Bessarabia, rather for political reasons than out of nostalgia.
Odessa is hit by a series of bomb blasts, targeting mainly objects of the public sphere such as banks, shops or activists’ offices. Also strategically important objects as rails or a ATO recruitment centre were hit. The pace is increasing since December, feeding concerns over a wider destabilization of the south-eastern region.
