A chemical plant in northeastern Spain exploded Tuesday night, killing one person and severely burning at least six people, authorities said.
A tweet of emergency services for the region of Catalonia previously described the massive explosion in the port city of Tarragona as a “chemical accident.”
Interior Minister of the region of Catalonia in Spain, Miquel Buch, tweeted that one person was still missing. Emergency services said doctors were treating two of those injured by major burns.
The civil protection agency was advising people living in parts of the city of 800,000 and nearby towns to close their windows and refrain from leaving as preventive measures.
The videos showed the aftermath of the explosion, with flames and a large column of black smoke coming out of an area dotted with large industrial tanks. Fire departments sent 24 brigades to the area, the regional emergency service said.

Tarragona is about 71 kilometers southwest of Barcelona.
