(CNN) -- A commercial airliner carrying 104 passengers has been hijacked on the tarmac at Mexico City's airport, CNN affiliate TV Azteca reported Wednesday.
Three Bolivian abductors aboard the Boeing 737 Aeromexico jet have threatened to blow it up if their demand to speak to President Felipe Calderon is not met, the station said.
The station added that the abductors had begun to release passengers from the jet.
The incident began at 1:40 p.m. (2:40 p.m. ET), when the plane -- Flight 576 -- arrived from Cancun, it said.
