Emergency crews responded Tuesday morning to an explosion that injured at least two people at the former YWCA building in downtown McKeesport.
The two people were taken to hospitals by ambulance after sustaining injuries related to the explosion, according to state emergency alerts.
The incident at 410 9th St. was first reported around 8 a.m., according to Tribune-Review news partner WPXI-TV.
The news station reported that witnesses said they saw debris flying from the building.
A police officer at the scene told WPXI that a crew installing a wheelchair-accessible ramp at the rear of the building struck a gas line. Gas and electric service have since been turned off to the building.
The building is home to a Penn State Greater Allegheny facility, the Ninth Street Clinic, and offices of medical marijuana provider PurePenn/Trulieve.
