Authorities are investigating a serious security breach at Humberto Delgado airport, in Lisbon. A man managed to invade a forbidden access zone in the air terminal.
The invasion lasted about 15 minutes, during which the individual managed to circulate through an area where staying is not permitted. The case is being treated by the competent authorities as a significant violation of security protocols.
Airport authorities declined to comment on the incident. The investigation is underway to determine the circumstances that allowed unauthorized entry into the restricted zone.
