Speaking to the Lusa News Agency, the commander of the Ponte de Sor Fire Brigade, Simão Velez, said that the victims were stabilised at the scene by emergency teams and will be transported to hospital.


The occupants of the aircraft are two men, one aged 32 and the other 39, he said.


According to the Alto Alentejo Sub-Regional Emergency and Civil Protection Command, the authorities were alerted to the plane crash at 11h06 am.


The rescue operations, according to the Civil Protection website, mobilised 25 operatives, supported by 10 vehicles and a helicopter.


The accident occurred a few kilometres from the Ponte de Sor Municipal Aerodrome, where the Portugal Air Summit is taking place until Sunday.


Contacted by Lusa, the director of the Ponte de Sor Municipal Aerodrome, Sandra Catarino, said that the crashed aircraft was not related to the activity of this infrastructure and that it was "a private flight".


"It has nothing to do with the activity or programme of the Portugal Air Summit and does not affect the air activities planned for the weekend," she added.


The circumstances in which the accident occurred will be investigated by the Office for the Prevention and Investigation of Aircraft Accidents and Railway Accidents (GPIAAF), which has already sent a team to the scene, a source from this organisation told Lusa.
