Flights from UK airports among four targeted by suspected bomb threats

Four passenger planes across Europe, two of which departed from the UK, are being inspected following a series of suspected bomb threats.

A flight from London Heathrow to Warsaw-Chopin Airport made an unscheduled landing at the Polish capital's other airport, Modlin, on Tuesday, briefly forcing its closure.

Another flight, from Copenhagen to Warsaw-Chopin Airport, landed as planned and has been checked.

Spanish officials have also confirmed a Ryanair plane from Manchester to Murcia airport in southern Spain also faced a threat, while Bulgarian media reported a flight from Israel landed in the capital Sofia after a bomb threat was received by email.

It is unclear if these incidents are connected.

Warsaw-Modlin Airport was temporarily closed on Tuesday morning and has since resumed operations.

However, a section of the airport where the plane was parked has been closed off, the airport said.

The flight, operated by Polish carrier LOT, was carrying 118 people.

SAS, which operated the flight from Copenhagen, confirmed it had landed safely and all passengers had disembarked. A spokesman from Chopin airport said that one of the runways on the airport apron had been closed but operations were not significantly impacted.

The Ryanair flight had 121 people on board, including crew, according to Francisco Lucas, the Spanish government's delegate in the Murcia region.

The plane was being inspected and security protocol was under way, he said.

The local fire brigade said it had also been mobilised at Murcia-Corvera Airport.

Around midday on Tuesday, local media in Bulgaria reported that a flight coming from Israel had received a bomb threat by email before it landed in Sofia.

Lyubomir Nikolov, the Chief Secretary of the Ministry of Interior, was quoted as saying that counter-terrorism teams were checking the plane for explosives.

These four incidents come a day after a Wizz Air flight from London Luton made an emergency landing in Budapest, escorted by a Hungarian fighter jet, after a bomb threat.

Wizz Air said later that security checks had been made and nothing was found.
