Spanish officials say one person has died and at least three others are seriously injured after two explosions at a chemical and fuel factory outside the southeastern town of Almeria.

A police spokeswoman said the blasts happened Monday in the PITA industrial complex 30 kilometers (20 miles) outside the city. The city's Interior Ministry office said one worker died and three were injured.

The spokeswoman said firefighters were searching the area for others who could possibly be injured. She spoke on condition of anonymity because of police rules preventing her from being named.
