An explosion rocked the Amuay oil refinery in northwestern Venezuela, killing 39 people, including a 10-year-old boy, a Venezuelan official said Saturday. More than 80 people were injured, Vice President Elias Jaua told state-run VTV. "People are very scared," said Falcon State Gov. Stella Lugo, according to the state-run AVN news agency. "They evacuated the areas that had to be evacuated, but the situation, as the technicians are telling within the refinery, is controlled."
