Polls have closed in South Korea's presidential election.
Voters turned out in droves, despite the nation's worst-ever coronavirus surge.
And exit polls predict a nail-biter finish.

A coalition of 3 local broadcasters says the race between the ruling party's Lee Jae-myung and the main opposition's Yoon Suk-yeol remains too close to call.
Exit polls show less than a point separating them, with Yoon getting forty-eight-point-four percent of the vote and Lee forty-seven-point-eight percent.
It will likely be several hours until the winner can be determined.
Voter turnout is expected to be the highest in decades.
People wore masks and plastic gloves so they could have their say safely.
The day before, South Korea logged a record 340,000 new COVID cases.
People already infected or in isolation voted separately after polling stations closed.
The pandemic's effect on the economy was a key campaign issue.
Candidates also debated how best to strengthen national security as the North continues to boost its missile program, and with all eyes on the Russian invasion.
