An explosive went off at a coronavirus testing centre north of Amsterdam early this morning, shattering windows but causing no injuries in what police called an intentional attack.
An explosives team was on site in the town of Bovenkarspel, 55km north of the capital, to examine the device, police in the province of North Holland said.
The metal remains of the explosive, about 10 cm by 10 cm in size, were found in front of the building and "must have been placed" there, a police spokesman said. "We don't know yet exactly what exploded, the explosives experts must first investigate," he said, adding, "what we're saying is that something like that doesn't just happen by accident, it has to be laid."
