BERLIN — German authorities say at least 19 people were injured, four seriously after a fireworks show went awry at a fair in the western city of Düsseldorf.

Fire squad and emergency services deployed after the incident late Friday at the Rheinkirmes event along the Rhine River, where images from the scene showed fireworks going off nearly at ground level along its banks.

A child was among the injured, the DPA news agency reported.

Düsseldorf fire services said police were investigating the cause of the accident.

“Our thoughts are with those affected and their families. We wish all those affected a speedy recovery from the consequences of the accident. We deeply regret the accident,” said Peter Dietlmaier, a spokesperson.

Organizers ended the fair, which features rides and more, early for the day, and were deciding whether to continue the traditional fireworks at next year’s event, he said.
