NEW YORK (AP) - Authorities say an out-of-control van plunged off a highway into a ravine on the grounds of the Bronx Zoo in New York City, killing seven people aboard, including three children.

Fire Department spokesman Jim Long says the victims were an 84-year-old man; three women, ages 80, 45 and 30. He says a 12-year-old girl and a 10-year-old girl were also killed, and a younger girl whose age wasn't immediately known.

Police say the van bounced off the median Sunday, crossed all southbound lanes, went through the guardrail, fell more than 50 feet and landed upside down. A spokesman says it crashed onto a part of zoo property that's closed to the public and not near exhibits.

The southbound side of the highway was closed while police investigated but has reopened.
