More than 50,000 residents in the northwestern German city of Hanover were evacuated from their homes on Sunday –about 10 percent of the city’s entire population – as three unexploded bombs from World War II were removed from a construction site in the town’s center.

Officials had initially suspected that two more bombs were buried beneath a nearby park, but a search on Sunday turned up nothing.

By 6pm local time (1600 UTC), residents were allowed to return to their homes.

There was a brief scare Sunday when bomb-disposal experts struggled to defuse one of the bombs manually due to its damaged fuse. A water jet cutter was brought in and used to open up the bomb and defuse it.
