"The festival has a maximum daily capacity of 95,000 people, so we had to stop ticket sales for the day at 10:00 in the evening on Monday. Looking at the way tickets are going, we can expect similar sell-out crowds on Friday and Saturday, too," chief organiser Tamás Kádár said.

Dua Lipa was the headliner on Wednesday. Justin Bieber and Stromae will play the main stage on Friday, and Calvin Harris and Lewis Capaldi will headline on Saturday.

Artists from 54 countries are performing for festival-goers from 103 countries at this year's six-day Sziget, which takes place on an island in the Danube.
