NEW YORK: Seven people, including two students, were injured Tuesday in an apparent accidental gas explosion at a college north of New York City, authorities said.

"There were seven injuries. All of them minor injuries. They were transferred to the hospital to be checked out," a police spokesman told AFP about the blast at Nyack College.

He said the cause of the explosion was unknown but that "they believe there was a natural gas line" problem.

The school said the blast hit at about 1545 GMT "in Sky Island Lodge, a building that houses the School of Business and Leadership, on the Rockland County campus.

There was no fire associated with the explosion." "Five employees and two adult students were in the building at the time and all are accounted for.

There were injuries, but no fatalities. All individuals were taken to the hospital for examination as a precautionary measure."

The school, founded in 1882, is a private Christian institution.
