Moldovan police detained a man on Sunday after two Molotov cocktails were reportedly thrown at the Russian embassy, where voting was underway for Russia's presidential election.
Media in Moldova, which borders Ukraine, reported that the embassy was attacked with Molotov cocktails. There were no injuries.
"A man threw two containers of flammable substances over the fence of the Russian Embassy in Chisinau," police said in a statement.
The 54-year-old Moldovan — who said he also has Russian citizenship — was "immediately detained" and being held for questioning, police said.
"He justified his action by some dissatisfaction he has with the actions of the Russian authorities," police added, with investigations ongoing.
The elections is taking place from Friday to Sunday and set to hand President Vladimir Putin another six-year mandate despite the tumult triggered by Russia's invasion of Ukraine.
Moldova this week protested Moscow's decision to open several polling stations in separatist Transnistria during the Russian presidential election.
The country of 2.6 million situated between Ukraine and Romania wanted the vote to be organized only at the Russian embassy in Chisinau.
