Ukrainian rescuers try to reach vehicles stuck in a blizzard on a road about 85 km of West-Ukrainian city of Lviv, Ukraine on 16 December 2012.
Deep snow drifts stopped traffic and trapped drivers on the international highway Kyiv-Chop between cities Brody and Busk in the Lviv region.
About 150 vehicles were stuck in snow for 30 hours on highways, the emergencies ministry said. Weather officials have warned the blizzard will continue in the region for at least two more days.
Temperatures as low as -35C threatened to freeze fuel lines and stop engines from running, only increasing the risk to drivers waiting to be rescued.
