More than 2,000 people were evacuated while Polish navy experts removed three Second World War-era bombs from the Baltic Sea bed at the holiday resort of Kolobrzeg.
The spokesman for the local navy unit, Jacek Kwiatkowski, said the bombs were hoisted out of the sea and onto a special truck and taken to a test range for controlled detonation.
Dariusz Trzeciak, a Kolobrzeg city official, said about 2,000 residents and 200 holidaymakers were evacuated in their own cars or in buses. They were later allowed to return.
Kolobrzeg, which was part of Germany during the war, was the site of fierce fighting in the war’s last phase.
