Montenegrin rescuers have so far pulled nine bodies from the wreckage of a Romanian bus that crashed into a deep ravine Sunday afternoon, police confirmed, dpa reported.
Television broadcaster Vijesti reported, quoting rescuers and police at the scene, that around 20 people were dead and that many of the around 30 passengers that were brought up alive were very seriously injured.
The extraction of the injured and dead was difficult because of inaccessible terrain, the commander of police in nearby Kolasin, Zeljko Darmanovic, told reporters.
The Romanian bus veered of the road at 5 pm (1500 GMT), crashed through the guardrail and tumbled to the floor of the Moraca Canyon some 30-40 metres below.
The bus entered Montenegro around two hours earlier, Darmanovic said.
A Vijesti reporter said that bodies could be seen strewn along the path the bus cleared through the vegetation. Rescuers were forced to lift the injured by hand, along a human chain.
The accident occurred on the Kolasin-Podgorica road, where it descends from the mountains into the deep Moraca Canyon. The road is heavily frequented and notoriously dangerous.
Montenegro's Adriatic coast is a summer holiday destination for hundreds of thousands of tourists from the region each year.
