MADRID — An explosion hit a biodiesel production plant in northern Spain on Thursday, killing two people and forcing the evacuation of 250 children who had been on a field trip nearby, police said Thursday.
Police video of the explosion showed flames engulfing the facility in the north of La Rioja and sending large clouds of black smoke into the sky. The two people killed were both workers at the factory, police said.
Rescue workers struggled to evacuate the area, including a nearby amusement park.
“A few feet from the facility, there was a field trip with 250 children who had to be transferred out of danger to another area,” police said in a statement.
None of the children were reportedly injured. Officials are investigating the cause of the explosion.
The municipality of Calahorra, where the plant is located, said on Twitter that it had cordoned off a one-mile perimeter around the facility while emergency responders worked to keep the fire contained.
“At this moment, the situation is under control,” Mayor Elisa Garrido wrote on Twitter. “The plant and the industrial area have been completely vacated.”
