A bus carrying Americans to a Catholic shrine in southern Bosnia collided with another vehicle Monday, injuring 27 passengers and the Bosnian bus driver, hospital officials said.
"We are currently assessing the injuries, and all I can say now is that three people sustained serious injuries, possibly life-threatening," said Dr. Lidija Lincender of Sarajevo's Kosevo hospital.
The U.S. Embassy in Sarajevo said the American group was from Wisconsin.
Twenty of the injured were hospitalized in the Kosevo hospital, and seven were taken to the General Hospital, the embassy said.
Bosnian police said the bus, which had been carrying 34 passengers, collided with another vehicle in Tarcin, some 12 miles south of Sarajevo. No details about the accident could be released because an investigation was under way, police said.
The embassy said the bus passengers had been on their way to the southern Bosnian town of Medjugorje, where millions of faithful have visited a shrine since 1981, when six Bosnian Croats said they began seeing apparitions of the Virgin Mary. The Medjugorje apparition has not been officially recognized by the Catholic Church.
