Moldova, the EU and the United States said the Kremlin had waged a "hybrid war" campaign to destabilize the country and keep it in Russia's sphere of influence, including funding pro-Moscow parties, spreading disinformation and pouring millions of dollars into schemes to buy up 300,000 votes. Nearly 1.5 million Moldovans ultimately voted.

Moldovans were evenly split on Monday amid final counting in a geopolitically momentous referendum on European Union accession with 50.08% in favor and 49.92% against, electoral authorities said.

The country’s aspiration to join the E.U. will now be enshrined in the Constitution but the referendum was incredibly close.
