An overloaded sightseeing boat carrying dozens of Bulgarian tourists sank on Saturday in a lake on Macedonia's western border, and 15 people drowned, officials said.
The vessel, called the Ilinden, sank rapidly in just six meters (20 feet) of water in Lake Ohrid, police spokesman Ivo Kotevski said. The vessel split in two and sank about 200 meters (650 feet) from shore.
There were 57 passengers on board, Kotevski told The Associated Press. Of those, 15 drowned and 42 were rescued. Four passengers who were recovered unconscious are still in hospital but are not in danger, he said.
Earlier reports had put the number of passengers on the Ilinden at 73. Police later corrected the number.
"The 23-year-old skipper and his deputy have been questioned about the incident. In their first statements they said that a loud crack was heard (toward the rear) before the boat sunk rapidly," Kotevski said.
One witness said she and others rushed to the scene in a speedboat.
"The scene was horrible," Gordana Ruvcevska said. "We saw at least 10 bodies floating. We pulled out three survivors."
Most of the passengers on the 70-year-old boat, which had a 42-person capacity, belonged to a group of tourists from Bulgaria.
The vessel had been traveling from Ohrid, on the lake's eastern shore, to the medieval Eastern Orthodox monastery complex Sveti Naum about 30 kilometers (20 miles) south near the Albanian border, according to Macedonia's private A1 television. Lake Ohrid itself -- the deepest in the Balkans, located along the mountainous border between Macedonia and Albania -- has been a UNESCO world heritage site since 1979.
Macedonia's government held a special meeting on Saturday and declared Sunday a day of mourning. Transportation Minister Mile Janakievski offered his resignation.
