Emergency officials have evacuated 188 people from cars and buses stranded in deep snow in northern Serbia, where snow drifts have also blocked two passenger trains.

Emergency officials said Sunday that snow drifts in places are 3.5 meters high (11.5 feet high), prompting the authorities to close the main border crossing with Hungary.

The state railway company says they will also evacuate several dozen of passengers stranded on two trains going to and from Hungary who were stuck because of piles of snow on tracks.

Authorities said a number of roads throughout northern Serbia were also frequently blocked Friday, with cars lining up in columns for several kilometers.
