The ski runs in Bulgaria's ski resort Bansko will remain closed on Friday, a day after an undisclosed ecological organization claimed to have planted a bomb there.
The situation in Bansko is normal; the police are currently combing the area to find the bomb. The municipality administration, the rescue services and citizens of the town are also helping in the search.
Bansko's police chief and town's Mayor Alexander Kravarov are in the Banderishka Polyana area to direct the operation of the bomb's search.
Poor weather conditions however may delay the operation.
The environmentalists and unnamed bomb scarers threatened in a letter to the media on Thursday they have planted the bomb somewhere on Bansko's ski runs.
The letter was also sent to the environment minister, explaining the alert aims to trigger avalanches and is in protest against the ravaging construction works in the resort.
