At least 40 people are feared dead Saturday after a bus fell more than 1,000 feet from a ridge in Brazil, several news agencies reported.
Rescue workers were trying to reach possible survivors, but Brazilian authorities told Agence France-Presse that efforts were hampered because of darkness and the terrain of the wooded ravine.
About 50 people are believed to have been aboard the bus when it plunged down the cliff near Joinville, a city in Santa Catarina state, the BBC reported.
According to Brazil's G1 news website, 41 bodies were retrieved from the crash.
Another two are believed to have died in hospitals.
The driver is believed to have lost control of the bus on the curving road, though the cause of the crash was still under investigation, officials told Agence France-Presse.
About a dozen passengers were reportedly rescued from the wreck and taken to nearby hospitals to be treated, including four children.
According to G1, the bus was carrying tourists in the area of Serra Dona Francisca.
