THE HAGUE, Netherlands (AP) — Dutch police say an early-morning blast caused by a “homemade device” smashed windows at a coronavirus testing center in a small town north of Amsterdam. Nobody was hurt. The country’s health minister called the incident early Wednesday “crazy” and a leader of local health authorities that carry out testing labelled it a “cowardly act.” Police in the North Holland province tweeted that “an explosive went off” near the testing center in Bovenkarspel just before 7 a.m. They later said that a homemade device exploded close to the testing center’s glass facade. In January, rioters torched a coronavirus test facility in the fishing village of Urk on the first night of a 9 p.m.-to-4:30 a.m. nationwide coronavirus curfew, but the curfew was generally supported by the Dutch.
