Moldova's leaders have rejected Russian claims that Ukraine is planning to attack the country's breakaway pro-Russian territory, and called for calm. Russia's Defense Ministry alleged, with no evidence, that Ukrainian saboteurs dressed as Russian troops would attack from Transnistria, to provide a pretext for a Ukrainian invasion. Moldova has warned for weeks that Russia is plotting to seize power. And officials rejected Russia's claims as "psy-ops" as part of the war. "The Defense Ministry believes it is an element of a psychological operation rather than a real plan," said state secretary Valeriu Mija. Leading MP Doina Gherman told Moldovan media that the Russian allegations were "aggressive disinformation". There was no imminent threat and she urged the public to trust the government. Moldovan President Maia Sandu, on a visit to neighboring Romania on Thursday, spoke of unprecedented security challenges ahead. "Some wanted our country to fall and to install in Chisinau a puppet government enslaved to the interests of the Kremlin," she said. Moldova is not part of NATO but last June it was awarded EU candidate status on the same day as Ukraine, bringing it one step closer to joining the bloc. Earlier this week the Moldovan leader met US President Joe Biden, who promised to support her country's sovereignty. However, on Moldova's eastern flank lies a narrow strip of land called Transnistria, between the Dniester River and the Ukrainian border. This breakaway region has a contingent of Russian peacekeepers, and Moscow has warned that any threat to its security will be treated as an attack on Russia itself. With a population of just 2.6 million, Moldova is one of Europe's poorest economies and has been heavily exposed to the war in Ukraine. It has faced a major energy crisis because its power infrastructure dates back to the Soviet era. Not only did Russia restrict its gas supplies but its attacks on Ukraine's power grid had knock-on effects. Rampant inflation and a big influx of refugees from Ukraine have created further pressures, leading to protests organized by the populist and pro-Russian Sor party, led by fugitive oligarch Ilan Shor. There has also been an apparent escalation of incidents described by new Prime Minister Dorin Recean as "hybrid attacks". A Russian missile was fired at Ukraine through Moldovan airspace on the day the previous government collapsed earlier this month, in the face of what the former PM called "multiple crises". President Sandu has accused Russia of plotting to bring down Moldova's leadership with the aid of foreign saboteurs from Russia, Serbia, Belarus and Montenegro. She said their aim would be to attack government buildings, seize hostages and then spark protests to replace the government with one "at the service of Russia". Shortly after her speech, 12 Serbian football fans were barred from entering Chisinau for a match. Fighters of a boxing club from Montenegro were barred from entering Chisinau for a tournament too. The Kremlin accused Moldova's leaders of slipping into anti-Russian hysteria and warned them to be "very, very careful" with their statements. Political analyst Denis Cenusa said Moldova's weakest point for pro-Russian forces was its internal socio-economic stability. If Russia failed in the short term, he said it could succeed at the ballot box in local elections this year and the presidential vote in 2024. Dominated by Russian speakers, Transnistria proclaimed independence from Moldova in 1990 as the Soviet Union fell apart. A short border war led to a ceasefire in 1992 and that has been enforced ever since by 1,500 Russian troops stationed there. As long as Transnistria's future remains unclear, tensions will remain. Moldova's new prime minister sees demilitarizing the area as a priority and the foreign ministry has said it will continue to seek a peaceful solution. But President Putin has pointedly revoked a 2012 decree committing Russia to finding a solution for Transnistria based on respect for Moldova's sovereignty and territorial integrity. Map showing Moldova and Transnistria As soon as Russian forces invaded southern Ukraine a year ago there were fears they would try to seize Odesa and the entire coast to Transnistria. That has not happened, but what Moldova's leaders are warning of now is reminiscent of what happened in April 2022. A series of mysterious explosions were reported, which separatist authorities in Transnistria said targeted their state security HQ, old Soviet-era radio masts and a military unit. Ukrainian "infiltrators" were held responsible then as well by Transnistria's authorities. Kyiv blamed Russian special services, warning they were seeking to threaten Moldova and destabilize the situation. Earlier this week a pro-separatist social media channel said it had seen Ukrainian military equipment on the motorway linking Ukraine to Moldova, but an unconvincing photo showed only a couple of small armored vehicles and a Ukrainian flag. Russia's Defense Ministry claimed it had detected a "significant amount of [Ukrainian] personnel and military vehicles" near Transnistria and said they carried a direct threat to Russia's peacekeeping force, but again it offered no evidence. The head of Transnistria's peacekeeping body, Oleg Belyakov, said there was no panic among its population but Russia's warnings did "give reasons for serious concerns". — BBC
