More than 170 bombs from World War II were discovered underneath a children's playground in northern England, officials said, and it is believed that more will be unearthed.
The first of the bombs – which still contained a charge – were discovered at the playground in Wooler, Northumberland in January, CBS News partner BBC reported. A total of 176 bombs have now been found so far and experts fear more will be unearthed, according to the BBC.
The playground was in the process of being updated when staff found a suspicious object while digging the foundation.
"It's quite something to think the children have been playing on bombs and it's been a really challenging situation," local councilor Mark Mather told the BBC.
The Wooler Parish Council said in a statement that Brimstone Site Investigations was hired to survey the playground and that it quickly became apparent that the "scale of the problem was far greater than anyone had anticipated."
Officials said 65 practice bombs weighing about 10 pounds each were found in an area of less than 10 square meters. Smoke cartridges were recovered from the same pit.
Another 90 practice bombs were found in about a 20 square feet area.
"Due to the large amount of ordnance buried, the site survey could not be completed in the anticipated 2 days and a further deployment would be necessary," officials said in a statement.
