'Insane' blast damages Dutch coronavirus test centre

The early morning blast Bovenkarspel, 60 kilometres (40 miles) north of Amsterdam, was caused by a metal cylinder

An explosion struck a Dutch coronavirus test centre in a "cowardly act of destruction" on Wednesday, shattering windows but causing no injuries, police and government officials said.

The early morning blast in the town of Bovenkarspel, 60 kilometres (40 miles) north of the capital Amsterdam, was caused by a metal cylinder left outside the building, police said.

The incident comes weeks after another testing centre was burned down during violent riots across the Netherlands against a coronavirus curfew.

"Police were called at 6.55 am by a security guard from the corona test centre to say that an explosion had taken place. He had heard a loud bang and then saw that several windows of the building had broken," a police statement said.

"Outside the building was a metal cylinder that had exploded. No one was injured in the incident."

North Holland police spokesman Menno Hartenberg said the explosion appeared to be deliberate.

"It's not possible that this was by accident, the object was placed there and exploded near the front of the test centre," Hartenberg told AFP by telephone.

"We are not ruling anything out and can't say anything about a motive, an investigation is underway."

Hartenberg added: "It was a metal object somewhere between a tube and a canister."

Police forensics officers in white overalls were conducting a fingertip search of the area, which was cordoned off, an AFP journalist at the scene said.

Dutch Health Minister Hugo de Jonge condemned the attack, saying public health authorities were "terribly shocked".

"For over a year now, we have relied heavily on the people on the front lines. And then this. Insane," de Jonge said on Twitter.

The Dutch GGD public health department said it was "horrified" by the "aggressive and intimidating" incident.

"Our people must be able to do this crucial work safely. This cowardly act of destruction affects us all," GGD national president Andre Rouvoet said on Twitter.

A bomb squad was sent to determine whether any explosive material remained at the scene, public television network NOS reported.

The part of the Netherlands in which Bovenkarspel is located is currently suffering one of the country's most serious outbreaks, with 81 infections per 100,000 inhabitants, compared to a national average of 27.2, NOS said.

The Netherlands has recorded more than one million coronavirus cases since the start of the pandemic and over 15,000 deaths.

Some 1.3 million people have received at least one dose of vaccine.

In January a Covid testing centre was set on fire in the conservative protestant fishing village of Urk as protests broke out over the start of an overnight curfew in the Netherlands.

The Netherlands suffered several nights of rioting, the most violent the country has seen in decades.

The blast in Bovenkarspel came as the Dutch government on Wednesday began easing its toughest anti-virus measures since the pandemic began, ahead of elections in two weeks.

Hairdressers and other non-contact professions were allowed to reopen after several months of closure.

Anger over the Covid measures has been growing in the Netherlands, as well as support for conspiracy theories about the virus.

A Dutch court last month backed a case by a Covid-sceptic group saying that the curfew was illegal and must be lifted, although an appeals court later dismissed the ruling.

Wednesday's explosion was also not the first case of suspected violence linked to the pandemic around the world.

In January, a man was arrested in Wales after a suspect package was sent to a Covid-19 vaccination production site, forcing a partial evacuation.

According to a report published Tuesday by a health NGO, health workers battling the coronavirus were subjected to more than 400 acts of violence related to Covid-19 worldwide in 2020.
