In Moldova’s separatist pro-Russian Transdniestria region, the election triggered a diplomatic dispute with Chisinau over its objections to the Kremlin’s plan to open 15 polling stations for Russian nationals there. Moscow says the 220,000 residents of Transdniestria, a sliver of land which broke away from Moldova in 1990 at the end of Soviet rule, hold Russian passports and are entitled to vote.
