Baku, August 4 (AZERTAC). A tour bus carrying more than 30 passengers flipped over on an upstate highway Wednesday night and landed upside-down in a ditch, injuring several people and trapping at least one woman underneath it.

Four people were seriously injured and 36 others suffered minor injuries, a dispatcher for the Broome County Sheriff`s Department said.

The bus was coming from Niagara Falls and its passengers included New Jersey residents and Polish tourists who were visiting family in New Jersey, said a Red Cross official.

The passengers were sheltering at a fire station, waiting for transportation back to New Jersey, said Marilyn Weiner, shelter manager for the Red Cross in Binghampton.

At about 12 a.m. some passengers who had been taken to the hospital for evaluation were returning to the fire station, she said.

The accident, the latest in a string of bus crashes in the Northeast this year, occurred on Interstate 81 in a southbound lane near Whitney Point, a scenic village of about 1,000 residents.
