Police in Moldova have detained the leader of the country’s pro-Russian Gagauz ethnic minority at Chisinau’s international airport. The arrest, which took place late Tuesday, follows the unexplained disappearance of two other pro-Russian lawmakers wanted by authorities. The incident adds to rising political tensions in the ex-Soviet republic, where Moldova’s pro-European government has been cracking down on alleged Russian influence. Officials have not disclosed further details on the charges against the detained leader.
