In the worst disaster on the Danube in more than half a century, the smaller tourist boat called Mermaid, with 35 people on board, sank after being hit by the cruiser under a bridge in Budapest during heavy rain.

The Ukrainian man, who has been in custody since 2019, told the court that he was "deeply sorry" about the tragedy

Twenty-five of those killed were South Koreans. The Mermaid's captain and its crew member also died and one Korean is still unaccounted for.
