A World War II bomb exploded early Friday in the eastern Czech city of Ostrava after a man tried to cut it during excavations, killing him and injuring another.
Police said on Twitter that the dead man may have mistook the bomb for an old sewage pipe.
They added: “He used an angle grinder to cut metal and the bomb went off.
“We can confirm it was an aerial bomb blast,” police spokeswoman Eva Michalikova told AFP.
Local media reported that a 49-year-old man had died while a 31-year-old man suffered minor head injuries.
Police evacuated about 50 people from homes 300 meters away from the site.
World War II ammunition and bombs are commonly found in the northeastern Czech Republic, where the Red Army attacked in the spring of 1945.
Last year alone, police evacuated hundreds of people on three occasions because of unexploded bombs in the air.
