Three workers trapped in a collapsed light rail tunnel under construction in Ottawa have been rescued.
Ottawa paramedics spokeswoman Manon Lavergne says one worker suffered a minor hand injury in the incident, which happened Thursday afternoon.
Lavergne says the injured worker was taken to hospital for treatment.
The other two were not injured.
Ottawa city Coun. Mathieu Fleury said at the scene (on Waller Street) near the University of Ottawa that the majority of workers escaped and the three were trapped in a "safe zone."
The city said on Twitter that the collapse was related to construction.
