Spanish biodiesel plant explosion kills two

Reports have emerged on May 26 that an explosion at a Spanish biodiesel plant has killed two people.
The incident is said to have taken place in the north-eastern region of La Rioja, Reuters reported.
It was not immediately clear what had caused the fatal explosion.
Local Spanish television showed footage of thick plumes of black smoke rising from the site.
It was also reported that a group of 250 children visiting a bird park nearby had to be evacuated, the central government's regional office said. No one in the party was injured.
The plant is operated by privately-owned company Iniciativas Bioenergeticas which produces biodiesel and glycerine there from recycled vegetable oils.
The company has not released any details about the incident.
