7 dead and 21 missing after tour boat sinks in Hungary

Hungarian rescue crews on Thursday searched for survivors after a tourist boat collided with another vessel in central Budapest and sank in the Danube River.

At least seven people were confirmed dead and 21 others were missing, rescue officials said.

The boat, named Hableany (Mermaid) and operated by a South Korean tour agency, was returning from an hour-long night tour when the accident occurred.

Two crew members and 33 passengers were on board, most of which were from South Korea.

Authorities said the Hableany was traveling close to a Viking cruise ship as they approached the Margit Bridge, not far from Budapest's iconic neo-Gothic parliament building on the riverbank.

The two ships were sailing side by side and in the same direction. But the tour boat veered into the much larger Viking and the two collided. This caused the Hableany to tip to its side, sending several passengers into the water, and then quickly sank.

"As the Viking comes into contact with (the Hableany), it overturns it and in about seven seconds, as it turns on its side, it sinks," Police Col. Adrian Pal said.

It remains unclear why the tour boat veered into the cruise ship. Police say they have launched a criminal investigation into the incident, one of the country's worst boat accidents.
