At least 21 flights across Europe have been impacted by bomb threats - a list of what journeys we know have been affected

It comes days after seven flights were affected by similar threats

Both London Heathrow and Birmingham Airports say they received threats earlier on Thursday, with Heathrow saying its was "deemed not credible"

Airport authorities in Rome say they received one via email from a group called "Fighters of the Male State", claiming to be targeting a "feminist regime"

That name likely refers to the Russian group Muzhskoi Legion, our security correspondent Frank Gardener writes - but even if the email is genuine it is unlikely to provide the leads to track down who is generating these hoaxes

An Aer Lingus flight from Dublin to Rome was diverted to a French military air base - one passenger tells the BBC "we were all trying to be as calm as we could"

Meanwhile, military fighter jets escorted one plane into Rome Fiumicino Airport and three aircraft to airports in Sofia
