Nine people were dead and 28 missing after a tourist ferry packed with around 170 passengers for the holiday weekend capsized Sunday on a reservoir near the Colombian city of Medellin, officials said.
A major rescue effort involving Colombia's air force and firefighters from nearby cities was looking for survivors at the Guatape reservoir where the four-story El Almirante boat sank.
As it went down, a flotilla of recreational boats and jet skis rushed to the scene to pull people from the vessel and deliver them safely to the shore, avoiding an even deadlier tragedy.
Police commander Jorge Nieto told Blu Radio that authorities were still in the process of identifying the victims and the nationalities of those on board were not yet known.
The air force sent a helicopter to the Guatape reservoir near Medellin, the country's second biggest city, while the local mayor said firefighters and scuba divers were heading to the town.
