Media organisations in Ireland and UK also affected as apparently coordinated effort to cause chaos continues
A fresh wave of bomb threats has disrupted air traffic across Europe but the affected planes landed safely and searches revealed no explosive devices.
The latest alerts affected at least 18 flights to or from Bulgaria , Czechia, France, Italy, Hungary, Cyprus, Romania, the UK and Portugal. Danish police investigated a threat against Copenhagen airport but the airport said it was operating normally.

The warnings followed separate threats on Tuesday and Thursday that forced at least 35 flights to be diverted or searched, raising questions over an apparently coordinated effort to cause chaos for travellers.
The latest threats affected at least nine flights to and from Prague, four flights over France , two flights en route to Sofia and a flight from Lisbon to Rome. Hungary scrambled fighter jets three times to escort civilian flights in its airspace, the defence minister, Romulusz Ruszin-Szendi, said on Facebook.
The affected flights had knock-on effects but were a tiny percentage – just 0.0674% – of the 26,709 flights that according to the air traffic control agency Eurocontrol were scheduled in Europe on Friday.
A separate spate of threats on Friday against media organisations in Ireland disrupted broadcasts and prompted staff evacuations and police searches of offices and newsrooms.

“It shows how relatively simple it can be to cause disruption and undermine the normal operation of society.” European security agencies would seek to identify those responsible and hold them accountable, said Martin.
The British broadcaster Sky said on Friday it had also received a security threat and reported the matter to the relevant authorities.
