Their plans only failed because of "a mixture of good fortune and technical mistakes which meant the devices did not explode," he said.

Abdulla will be sentenced at a later stage.

Nightclub bomb plot

Two Mercedes cars packed with gas canisters, fuel containers and nails were left in London's West End area in June, 2007.

One was parked outside Tiger Tiger, a nightclub near Piccadilly Circus which had more than 550 revellers inside, while the second was left at a nearby night-bus stop.

The second car was deliberately placed to catch people fleeing the first explosion, had it gone off, prosecutors and police believe.

Neither vehicle exploded despite repeated attempts to set off detonators using mobile phones.

Abdulla and Ahmed escaped the scene in rickshaws and drove to Scotland the next day.

They later smashed a Jeep Cherokee, also packed with fuel containers and gas canisters, into the international terminal at Glasgow Prestwick airport.

The blazing car was rammed into the airport terminal doors but attempts to detonate petrol bombs on the vehicle failed.

'Stunt attacks'

Abdulla had denied plotting to kill anyone and told the court he "loved England" and believed they were going to Glasgow to flee the country.

The junior doctor at the Royal Alexandra Hospital in Paisley, west of Glasgow, said the attacks were a "stunt" to bring attention to Britain's role in Iraq.

He said he hated the United States' government and supported insurgents fighting in his homeland.

Prosecutors said the pair's aim had been to cause fear on a scale similar to that generated by the London bombings in July 7, 2005, which killed 52 people.
