BERLIN, Dec. 9 (UPI) -- Buildings were evacuated and traffic snarled up when an unexploded World War II bomb weighing 1,100 lbs was unearthed in a main Berlin avenue Thursday.
Road workers found the bomb dropped from a British plane when digging under Berlin's fashionable Unter den Linden.
The main building of Berlin's 35,000-student Humboldt University was evacuated, and the Linden Opera House called off a rehearsal of Russian composer Modest Mussorgsky's "Boris Godunov."
Surrounding streets in central Berlin were closed for several hours, resulting in massive traffic jams.
The bomb,which was eventually defused by bomb disposal experts, had lodged in the ground close to a bronze statue of Frederick the Great of Prussia without causing any damage, TV stations reported.
Observers say Berlin still hides as many as 1,000 undetected bombs. The German capital during World War II was a main target of heavy air raids.
