Moldovans voted by a razor-thin majority in favor of securing the country’s path toward European Union membership, electoral data showed Monday, after the pro-Western president accused foreign interference and “criminal groups” of trying to undermine the vote in the former Soviet republic.

Moldova voted in favor of adding a path to the European Union to its constitution, and gave the incumbent president the most votes in elections Sunday, but neither result was the win leaders wanted.

The European Union has condemned Russia's attempts to sway the outcome of the presidential election and the referendum on Moldova's European accession, promising to continue to support the country's democratic progress.
