The Bulgarian authorities have demolished more than 15 illegal buildings in the country's largest and most popular summer resort Sunny Beach.

The buildings have been located mostly on the sand in the northern beach of the resort.

The action had begun precisely at midnight Monday into Tuesday, which was the deadline given to owners to remove the establishments on their own. Most, however, failed to undertake any move in that direction.

From a total of 45 illegal buildings on the northern beach only 3 had been dismantled voluntarily. Those remaining will be demolished after the end of the active season over the need to use heavy construction equipment.
