A 21-year-old Orthodox Jewish girl from Manhattan is among three people who died in a bus accident in Honduras on Wednesday.

Two Columbia University students and a U.S. health-care worker died Wednesday in this Central American nation when their bus crashed while taking them to the airport to fly home after a volunteer mission helping poor Hondurans.

Isa Alvarado, spokeswoman for the Public Ministry morgue in Honduras, said the dead were three American women aged 20, 21 and 45. Their identities were not immediately released.

Twelve more Americans were injured. Reinaldo Canales, administrator for the Valle de Angeles Adventist Hospital, said they were in stable condition.

U.S.-based Global Brigades, which organizes international health and development missions, posted a notice on its website saying the accident involved a bus transporting “Columbia University students and other volunteers,” and that those killed were two students and a health care professional.

“Our heartfelt sympathy goes out to all those affected by this tragedy,” said the statement, attributed to co-founder Steven Atamian. Phone messages left at Global Brigades headquarters in Seattle were not immediately returned.

The crash took place on a highway east of the Honduran capital, Tegucigalpa. Officials reported that the bus was traveling from the town of San Juancito when it veered off a road and fell about 80 feet (25 meters) into a gully.

Firefighters’ spokesman Capt. Gustavo Barahona said the crash was believed to be the result of mechanical failure.

He added that at the time of the accident, they were on their way to the airport to return to the United States after carrying out a health mission for poor residents of San Juancito and Valle de Angeles.

Alvarado said forensic workers were preparing the bodies to be returned to the United States.

The U.S. Embassy in Honduras said in a statement it was in close contact with local authorities and working to provide consular assistance to any who need it.
