A spokesperson for the Czech Foreign Ministry said that authorities had received the “deeply tragic” news that at least three Czech citizens had died in the collision involving a yacht and a catamaran off the Croatian coast.

The Czech consul is on site, spokesman Adam Corgo said, offering condolences to the victims' families.

The accident occurred in the waters between the central islands of Solta and Brac when a "passenger vessel operated by a private domestic company collided with a French-flagged sailboat, which then sank", the Croatian sea and transport ministry said earlier.

There were 118 passengers and seven crew members on the passenger vessel, and eight people on the sailboat, three of whom were killed, the statement added.

One person was still missing while the remaining four were rescued from the sea.

Croatian Prime Minister Andrej Plenkovic voiced condolences to the victims' families and his Czech counterpart Andrej Babis.

"An intensive search for one person is still ongoing," he said on X.

According to the Split hospital, the four injured Czech nationals were not in a life-threatening condition.
