A flight from Prague to Cyprus landed safely on Friday after a bomb threat, with all passengers unharmed, as a week of false alarms continued to disrupt air traffic across the continent.

Speaking to the Cyprus Mail, police confirmed the bomb threat was made before the flight’s departure and said Czech security services searched the aircraft before it continued its journey.

Standard procedure was followed throughout as well as upon arrival in Larnaca.

Sources at the defence ministry told us the Joint Rescue Coordination Centre (JRCC) had been placed on standby. The JRCC is responsible for coordinating search and rescue operations in the event of aviation and maritime accidents.

Wizz air flight W64600 arrived at 2.05pm, 30 minutes after its scheduled time of 1.35pm.

The flight was one of nine targeted at Prague airport on Friday, according to spokeswoman Denisa Heitmankova.

Four were arrivals, from Denmark, Britain and two from Spain, and five were departures, bound for Cyprus, the Netherlands, Romania, Italy and Britain.

She assured operations “remain normal and smooth”, and the airport and Czech police declined to give further details of the flights involved.

The incident forms part of an outbreak of false alarms across Europe this week.

Czech police checked four aircraft on Thursday following related warnings, while in Bulgaria, a transport ministry spokesman told the Bulgarian News Agency that two flights to Sofia, from London Stansted and Brussels, received warnings on Friday and both landed safely.

Portuguese police said a Ryanair flight due to leave Lisbon for Rome was also targeted.

Dozens of commercial flights have been affected this week, with authorities diverting certain aircraft as well as escorted others with fighter jets.

No group or individual has claimed responsibility, and officials have not said whether the alerts are connected.
