Three children, ranging in age from 6 to 8, died when the boat they were in capsized Tuesday on Costa Rica's Pacific coast, officials said.

The shipwreck happened where the Damas River empties into the Pacific Ocean in Puntarenas province, some 160 kilometers (99 miles) south of San Jose.

The accident may have been caused by the powerful currents in the area, Deputy Security Minister Celso Gamboa told reporters.

The boat was on a fishing trip and had nine people aboard - five adults and four children.

One of the children was rescued by the coast guard and officials confirmed that the bodies of the other three children have been recovered.

None of the people in the boat was wearing a life jacket, Gamboa said.

The survivors were taken to the hospital in Quepos, a community in Puntarenas near where the boat capsized. EFE
