An emergency services agency in northeastern Spain says a big explosion has rocked an industrial hub near the port city of Tarragona.
A tweet by the emergency services for the Catalonia region on Tuesday called the blast a “chemical accident”and advised residents to refrain from going outside as a preventive measure.
The service says no information immediately was available on possible deaths or injuries.
Local residents posted videos showing the aftermath of the blast, with flames and a big column of black smoke emerging from an area dotted with big industrial tanks.
