7 South Koreans lost their lives when a tourist boat capsized on the Danube river in Hungary's capital, Budapest.
After the incident, 19 people have not yet been found.
30 tourists and 3 tour guides, as well two Hungarian crew members, were on the boat when it was hit by another vessel while moored.
The incident took place at about 22:00 local time (20:00 GMT) on Wednesday.
7 people have been rescued, and a massive search operation is continuing on a river swollen by heavy rainfall.
The rain had led to strong currents on the Danube, a popular draw for tourists.
