The pro-European party of Moldovan President Maia Sandu has claimed victory and a new majority in parliament in Sunday's elections seen as critical for her country's future path to the EU.
Sandu had warned of massive Russian interference after voting, saying the future of Moldova, flanked by Ukraine and Romania, was at stake.
Igor Grosu, the leader of Sandu's Party of Action and Solidarity (PAS) which secured about 50% of the vote, said Russia had thrown everything it had at the election.
Opposition leader Igor Dodon had claimed victory even before results came in and called for protests outside parliament in the capital Chisinau on Monday.
However, the win by PAS is emphatic: Monday's protest was tiny and mostly attended by pensioners. And there is no sense at this point that they have any momentum.
With 99.9% of the 1.6 million votes counted, PAS had 50.17% of the vote - far ahead of the pro-Russian Patriotic Electoral Bloc on 24.18%, Moldova's central electoral commission said.
Turnout was 52%, higher than in recent years.
European Commission President Ursula von der Leyen welcomed the result. You made your choice clear: Europe. Democracy. Freedom, she wrote on X on Monday.
Polish Prime Minister Donald Tusk praised Sandu, saying she had saved democracy and stopped Russia in its attempts to take control over the whole region. A good lesson for us all.
Ukrainian President Volodymyr Zelensky said in a post on social media: These elections showed that Russia's destabilising activity loses, while Moldova in Europe wins.
In Russia, Kremlin spokesman Dmitry Peskov said: From what we see and know, we can conclude that hundreds of thousands of Moldovans were deprived of the opportunity to vote in Russia because there were only two polling stations open to them, which was of course insufficient.
Moldova also has a pro-Russian breakaway enclave called Transnistria along its border with Ukraine, complete with a Russian military presence.
Residents in this sliver of land have Moldovan passports. Many are strongly pro-Moscow and Socialist party leader Igor Dodon said there had been all sorts of harassment, stopping them from voting.
Moldovans have been buffeted by Russia's full-scale war in neighbouring Ukraine, but they are also grappling with spiraling prices and high levels of corruption.
President Sandu, 53, who won a second term of office last November, warned Moldovans the future of their democracy was in their hands: Don't play with your vote or you'll lose everything! The party in fact won a clear majority over all other parties and blocs contesting the election.
Thanking Moldovans for voting in record numbers, Dodon called on the PAS government to leave power, and for supporters of all opposition parties to take to the streets on Monday to defend their vote outside parliament at midday.
In a measure of the tension surrounding the vote, bomb scares were reported at polling stations in Italy, Romania, Spain and the US. Similar scares were reported in Moldova itself and three people were arrested on suspicion of plotting unrest the day after the vote. Grosu blamed criminal groups backed by Moscow for Sunday's incidents and appealed for patience and calm to let the electoral process continue.
In the run-up to the vote, police reported evidence of an unprecedented effort by Russia to spread disinformation and buy votes. Dozens of men were also arrested, accused of travelling to Serbia for firearms training and coordinating unrest.
The number of voters from Transnistria was well down on previous years, with only about 12,000 making the journey to polling stations, highlighting the challenges faced by Moldovans amid external pressures and internal divisions.
