Protesters continued to rally outside a vote-counting facility in Seoul for the fifth day Tuesday, demanding a re-run of last week's local elections over ballot shortages at some polling stations.

As of 10 a.m., some 200 protesters surrounded SK Olympic Handball Gymnasium in Songpa Ward, according to an unofficial police estimate. The number was sharply down from about 2,000 on Monday afternoon.

Tens of thousands of people had amassed at the stadium over the weekend to protest the ballot shortages and block election officials from removing ballot boxes.

The lack of ballot papers temporarily suspended voting at 26 polling stations nationwide on Wednesday, according to the National Election Commission (NEC).
