Explosion in the Netherlands injures at least 4 and causes widespread damage

UTRECHT, Netherlands (AP) — An explosion on a residential street in the center of the Dutch city of Utrecht injured at least four people Thursday, an emergency services official said. The cause of the blast was not immediately known.

The explosion, which caused a blaze and widespread damage, occurred mid afternoon, sending people running into nearby shopping streets. Firefighters tried to douse the flames but were not immediately able to enter damaged homes because of fears of structural damage.

Emergency services spokesman Sjaak Haasnoot said the four people injured were taken to the city's hospital. The extent of their injuries was not known. It was unclear if there were any casualties.

“It is very difficult at the moment to say how many victims are under the rubble," Haasnoot said. “The fire department cannot enter the building because it is still unstable.”

Firefighters said they were investigating how they could safely comb through the rubble of the shattered buildings to establish if any people are trapped. Residents whose homes were damaged were being accommodated in a nearby hotel.

Police were investigating, Utrecht Mayor Sharon Dijksma told reporters.
