(CNN) A "partial equipment failure" involving a jet bridge at Baltimore/Washington International Thurgood Marshall Airport (BWI) in Maryland on Saturday left six people injured.

The airport tweeted that the six people were taken to local hospitals with non-life threatening injuries. The jet bridge, an extendable hallway stretching from the terminal to the plane, was at Gate E-10 for Southwest Airlines Flight 822, according to the airline.

Southwest Airlines said the flight arrived at BWI from Punta Cana, Dominican Republic, with a request for paramedics to meet it to check out a passenger's "onboard medical situation." While medics were helping the passenger outside the aircraft, the airline said the jet bridge "experienced a failure."

The remaining passengers got off the plane using stairs.

"We are working swiftly to assist all passengers and crew," Southwest said in a statement to CNN.
