French voters are casting ballots in a presidential election runoff that could decide Europe’s future, choosing between independent Emmanuel Macron and far-right populist Marine Le Pen.

Voting stations opened across mainland France at 8 am local time, which was 2 am EST, under the watch of 50,000 security forces guarding against extremist attacks.

Polling agency projections and the first official results will be available when polls close at 2 pm EST, which is 8 pm local time.
