The tracks of Bulgaria's ski reasort bansko are preparing to re-open Saturday afternoon after police carried out a controlled blast to let an avalanche go down.

State BNT informed that several mortars were fired off, but only to unleash a small piece of snow mass.

The ski runs in Bulgaria's ski resort Bansko were closed on Friday, a day after an undisclosed ecological organization claimed to have planted a bomb there.

The situation in Bansko is normal, local authorities said but expressed concern over this apparent threat to the security of Bansko residents and guests.

The unnamed bomb scarers introduced themselves as environmentalists and threatened in a letter to the media on Thursday they had planted the bomb somewhere on Bansko's ski runs.

The letter was also sent to the environment ministry, explaining the alert aims to trigger avalanches and is in protest against the ravaging construction works in the resort.
