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.

Electoral data shows that Moldovans have voted by a razor-thin majority in favor of securing the country’s path toward European Union membership.

Moldova’s crucial referendum on joining the European Union is too close to call, partial results showed Monday, as President Maia Sandu condemned an “unprecedented assault” on the country’s democracy.
