It was an explosive situation.
German munitions experts had to defuse seven unexploded World War II bombs at the site where Tesla wants to build its new Gigafactory, CNBC reports.
German news site Deutsche Welle reports that the ordinance was "relatively small" and dropped by the US Air Force during the second World War.
The operation was reportedly routine for German authorities and the operation was completed "without any problems," according to a police spokesman, DW reports.
Tesla is working on opening a massive car factory — the fourth Gigafactory after Nevada, Buffalo, and Shanghai — near Berlin on a 300 hectare site. The plant "will build batteries, powertrains & vehicles, starting with Model Y," according to a November tweet by Tesla CEO Elon Musk.
The news comes after local residents took to the streets, as Electrek reports, to protest the construction of the massive car factory over environmental concerns.
Local water associations voiced concerns over "extensive and serious problems with the drinking water supply and wastewater disposal," Reuters reported.
Musk took to Twitter on Saturday to defend the construction project.
"Tesla won’t use this much net water on a daily basis," he tweeted. "It’s possibly a rare peak usage case, but not an everyday event."
