( Telegraph ) -A group of 45 Muslim doctors threatened to use car bombs and rocket grenades in terrorist attacks in the United States during discussions on an extremist internet chat site.
Police found details of the discussions on a site run by one of a three-strong "cyber-terrorist" gang.
They were discovered at the home of Younis Tsouli, 23, Woolwich Crown Court in south-east London heard.
One message read: "We are 45 doctors and we are determined to undertake jihad and take the battle inside America.
"The first target which will be penetrated by nine brothers is the naval base which gives shelter to the ship Kennedy." This is thought to have been a reference to the USS John F Kennedy, which is often at Mayport Naval Base in Jacksonville, Florida.
The message discussed targets at the base, adding: "These are clubs for naked women which are opposite the First and Third units."
It also referred to using six Chevrolet GT vehicles and three fishing boats and blowing up petrol tanks with rocket propelled grenades.
Investigators have found no link between the Tsouli chat room and the group of doctors and medics currently in custody over attempted car bomb attacks in London and Glasgow.
However, sources said it was "definitely spooky" that the use of doctors for terrorist purposes was being discussed in jihadi terrorist circles up to three years ago.
Part of the inquiry into the London and Glasgow incidents will focus on whether al-Qa'eda has recruited doctors or other medical professionals because they are less likely to attract suspicion and can move easily around the western world.
The three "cyber terrorists" - a British national and two who had been given the right to live in Britain - are facing lengthy jail sentences after admitting using the internet to spread al-Qa'eda propaganda inciting Muslims to a violent holy war and to murder non-believers.
They had close links with al-Qa'eda in Iraq and believed they had to fight jihad against a global conspiracy by kuffars, or non-believers, to wipe out Islam.
The three are the first defendants in Britain to be convicted of inciting terrorist murder on the internet. They waged cyber-jihad on websites run from their bedrooms.
Tsouli promoted the ideology of Osama bin Laden via email and radical websites. He said in one message he was "very happy" about the July 7 bombings in London in 2005.
Tsouli, along with Tariq Daour, a biochemistry student, and Waseem Mughal, a law student, were intelligent, computer-literate men who promoted violent propaganda.
They created chat forums to direct willing fighters to Iraq and discuss murderous bomb attacks around the world. Films of hostages and beheadings were found by police.
Daour, 21, of Bayswater, west London, who was born in the United Arab Emirates, yesterday admitted inciting another person to commit an act of terrorism wholly or partly outside Britain. Moroccan-born Tsouli, 23, of Shepherd's Bush, west London, and British-born Mughal, 24, of Chatham, Kent, admitted the same charge on Monday.
They are due to be sentenced today. They also admitted conspiring together and with others to defraud banks, credit card companies and charge card companies. Daour had instructions for making explosives and poisons, the court was told. Police found instructions on causing an explosion with "rocket propellant'' and constructing a car bomb.
In one on-line conversation, Daour, asked what he would do with ?1 million, replied: "Sponsor terrorist attacks, become the new Osama."
The three men outwardly appeared to be leading normal lives, studying and living with their parents. Tsouli had come to the UK with his family from Morocco in 2001.
Mughal had a degree in biochemistry from Leicester University and was studying for his masters.
Daour, who was granted British citizenship in May 2005, had applied to start a law degree.
