HANOVER, GERMANY - MAY 07: An elderly woman walks by a barricaded apartment complex as part of the evacuation of 50,000 people on May 7, 2017 in Hanover, Germany. Bomb disposal experts will check five locations in the city today where unexploded bombs from World War II might possibly lie underground. Today's evacuation is among the largest ever in post-World War II Germany. Unexploded World War II bombs, mostly from Allied aerial bombing, remain a deadly legacy and smaller scale evacuations are a regular occurrence in major urban centers across Germany throughout the year.
