Moldova’s pro-Western President Maia Sandu has won a second term in office in a pivotal presidential runoff against a Russia-friendly opponent, in a race that was overshadowed by claims of Russian interference, voter fraud, and intimidation in the European Union candidate country.

With nearly 99% of votes counted in the second round of the presidential election held Sunday, Sandu had 55% of the vote, according to the Central Electoral Commission, or CEC, compared to 45% for Alexandr Stoianoglo, a former prosecutor general who was backed by the pro-Russia Party of Socialists.
