Utrecht Blast Triggers Building Collapses and Emergency Search Efforts

A powerful explosion in the historic centre of Utrecht on Thursday afternoon caused multiple building collapses, ignited a significant fire, and left at least four people injured, according to regional emergency services. The incident, which occurred around 3:30 p.m. on Visscherssteeg, sent dense smoke over the city and prompted a large-scale emergency response.

What Happened

Several adjoining structures collapsed or were left structurally unstable, with debris, shattered glass, and rubble scattered across the surrounding streets.

Witnesses reported hearing one or more loud blasts moments before a fire broke out in a two‑storey residential building.

The force of the explosion was strong enough to be felt hundreds of metres away, including at the Utrecht City Council building.

Casualties and Emergency Response

• At least four people sustained injuries and were transported to UMC Utrecht for treatment.
• Authorities warned that additional victims could still be trapped beneath the debris, and search teams—including sniffer dogs—continued combing the site into the night.
• A nearby hospital activated an emergency trauma unit, and the Red Cross issued a call for volunteers to support affected residents.

Impact on Residents

• Dozens of residents were evacuated and temporarily housed at Hotel Karel V or with family and friends.
• Gas and electricity were shut off for around 40 nearby homes as a precaution, and a large section of the city centre was cordoned off to ensure safety during rescue operations.

Cause Under Investigation

• The exact cause of the explosion remains unknown.
• Some witnesses reported a smell resembling natural gas shortly before the blast, but officials have not confirmed whether a gas leak triggered the incident or occurred as a result of it.
• Authorities stated that foul play is considered unlikely but emphasised that all possibilities remain under investigation.
