Flight chaos, more bomb alerts in Europe: 2 more planes to and from Italy involved. LIVE

The bomb scares continue, which already caused chaos in the skies of Europe yesterday. A plane coming from Rome was forced to carry out a security operation at Lisbon airport this morning: the Ryanair flight landed in the Portuguese capital at 8 this morning. The alert was received by the Public Security Police via a phone call from a law enforcement officer, whose identity was verified by members of the Judicial Police. While another bomb threat was triggered for a Wizzair Prague-Rome flight. The report of the bomb on board, according to what we learn, came from an anonymous phone call to the Fiumicino control tower. The flight, which should have arrived in the capital at 11am, was diverted to Venice where it landed.

The Prime Minister's office in France said that four more bomb alerts relating to planes flying over the country's territory had been received. All aircraft landed safely and checks are underway, both on the aircraft and to determine the origin of the threat.

A total of 21 flights were affected by the bomb threats recorded in Europe on 3 and 5 November, of which 14 yesterday alone. This is the assessment provided by Eurocontrol, the European Organization for the Safety of Air Navigation, which is monitoring the situation in collaboration with the authorities and operators in the sector.

Meanwhile, in the past few hours, stories have emerged from the passengers of the Air Lingus Airbus A320, who returned to Rome during the night after being forced to land at the Evreux-Fauville military base following a bomb threat: "I was sitting more or less in front and in any case I could see the scene clearly. The light above the pilot's door came on and he called the first flight attendant into the cabin who rushed in. She went out very alarmed and called the others and they did there was no panic, but we understood that something unusual, strange, was happening anyway", said a passenger. "Our flight was diverted to a military airport, they made us get off, searched us with dogs. We were treated well, but it was a difficult day," added another passenger.
