Greece and Slovenia have sent a helicopter each to Montenegro after Podgorica asked NATO for help in battling the worst winter weather for decades.
The two aircraft have already arrived in Montenegro and will be used to reach remote areas cut off by heavy snow.
The Montenegrin government sent a request for equipment to NATO on Monday. In addition to the helicopters, the country is mainly looking for chains for construction machinery and motorised sleighs.
Prime Minister Igor Luksic said some NATO members had shown a willingness to help Montenegro before the government even asked for assistance.
