On Wednesday, a construction digger found an unexploded, 80-centimeters-diameter World War II era bomb in Warsaw, Poland, at the construction site where the National Stadium is being built.
It´s being built for the Euro 2012 football championships. Engineers removed the shell safely. Sometimes in Poland some unexploded WW II bombs are found. A 500-kg explosive left over was found before in Wroclaw by construction workers.
