Two U.S. helicopters arrived in Montenegro Wednesday to join rescue operations in the areas of the tiny Balkan state hit by the heaviest snowfall in 60 years.
The U.S. military deployed two Black Hawk helicopters in response to Montenegro's appeal to NATO for urgent help for thousands of snowbound people in the north of the country.
Croatia, Slovenia and Greece have already sent helicopters for the rescue mission.
Last week, Montenegro's authorities declared a state of emergency as four people died and more than 350 had to be evacuated from the villages blocked by up to 3.5 meters (11.5 feet) of snow.
In nearby Serbia, however, rising temperatures have led authorities to consider lifting a state of emergency imposed earlier this month.
