LONDON Two passengers on a flight from Pakistan to England today allegedly threatened to “destroy the plane” after an argument with crew, according to a Pakistani official.

The British military scrambled fighter jets to intercept the airliner, which was carrying more than 300 people, and it was diverted to an isolated runway at an airport outside London.

The two British passengers who allegedly were speaking in Urdu when they made the threat were arrested.

A British security official says the incident does not appear to be terror-related, although police are still investigating.

The incident further rattled the U.K., just days after a soldier was killed on a London street in an apparent terror attack.

Pakistan International Airlines flight P709 was on its way from Lahore, Pakistan to Manchester Airport when it was diverted by the fighter jets to Stansted Airport.

Essex Police boarded the plane at Stansted and arrested two men “on suspicion of endangerment of an aircraft,” according to a statement from the police, which did not elaborate.

A passenger told Pakistani TV that two men who had tried to move toward the cockpit during the flight were handcuffed and arrested after the plane landed.

The remaining passengers were reportedly being taken off the plane, and there were no reports of injuries.

Sources tell CBS News the pilot may have raised the alarm and 제주도출장마사지 been ordered to land after an altercation in the cabin.

It is standard protocol for flights involving potential terrorism in U.K. airspace to be diverted to Stansted, which is in a relatively rural area about 31 miles northeast of London.
