BOSTON — One person was killed and several others were injured in a multi-vehicle crash on Interstate 93 in Boston on Thursday afternoon, authorities said.

“There are several injuries reported, and unfortunately, one fatality,” state police said in a statement.

Boston firefighters and EMS were responding to the crash as the evening commute kicked into high gear.

Motorists were urged to seek an alternate route because the left two lanes of the highway were closed.

“Drivers should expect delays in the area,” state police warned. “This is an active situation.”

There were no additional details immediately available.

The cause of the crash is under investigation.
