MADRID, May 26 (Xinhua) -- Two people died on Thursday in an explosion at a plant making biodiesel on the outskirts of the city of Calahorra in the La Rioja region of northern Spain, local emergency services said.
The explosion happened at around 12:55 local time (1155 GMT) and the area was evacuated with a security perimeter set up one kilometer away from the explosion.
Some 250 school children from the city of Zaragoza, who were on a day-trip visiting the nearby Tierra Rapaz nature park, were among those evacuated.
Members of the fire departments from Calahorra and Logrono were at the scene along with members of the local police and Civil Guards. The fire brigade was fighting to prevent the fire after the blast from spreading to other container tanks at the site.
The two people killed are believed to be workers from a different company other than from the biodiesel plant. No injuries were reported. ■
