Islamic terrorists are using the internet to spread their hatred from behind bars.
Dozens of letters written by some of the world's most dangerous extremists - including those locked up for murderous plots in Britain - have been published on MuslimPrisoners.com
The hate-filled messages celebrate murder of innocent people and urge fresh atrocities against the West.
The website is being used as a networking tool for the jihadist militants - many with links to al-Qaeda - and encourages the public to send emails, with the promise that their letters will be passed onto the inmates.

Its users include notorious hate preachers Abu Hamza and Abu Qatada. who was released under strict bail conditions, which include a ban on him using the internet, this month.
Leaders of terrorist plots targeting passenger planes and London landmarks are also said to have used the website, including Hussain Osman, jailed for his botched attempt to blow up Shepherd's Bush Tube station in 2005.
It is claimed the website was set up by Abdul Muhid, a member of the banned Al-Muhajiroun group, who has served time in jail for inciting murder and hatred during protests over Prophet Mohammed cartoons.
The Sunday Times reported that among messages posted on the website, are some from Abdulla Ahmed Ali, caged for at least 40 years as leader of a suicide plot to blow up trans-Atlantic passenger jets.
Ahmed hails the 'humiliating defeat' inflicted on NATO forces in Afghanistan by the Taliban.
His message - posted last month - read: 'If the mushriks [non believers] can leave their families and sacrifice their lives and limbs to occupy, enslave and oppress the ummah [global Muslim community] then we too can sacrifice 100 times that to defend it.'

There are also jihadist messages from Bilal Zaheer Ahmad, jailed last year after calling on Muslims to copy Roshonara Choudhry and murder MPs who voted for the Iraq war.
Ahmad's letters also includes calls for inmates to lie about their reform so they can be freed early to the continue their holy war and reveal extremist material is freely available to inmates and that he is in direct contact with Choudhry.
Last July he wrote: 'I received a letter from that sister during the week. She said it feels like she was only arrested yesterday and the last year of her life has been the best.'
Choudhry, who attempted to murder former Labour minister Stephen Timms, is also reported to have posted on the website, describing the euphoria she felt from having the support of Muslims when she was jailed at the Old Bailey.
Another inmate, Hamza Davidson, 34, who is serving a life sentence, is said to have claimed to be studying books by Bilal Philips, a Jamaican preacher who calls for homosexuals to be executed and was banned from Britain.
Other letters reveal extremists are radicalising other inmates. A Commons select committee report on radicalisation this month claimed one prisoner was persuaded to become a suicide bomber within 72 hours of arriving at London's Belmarsh prison.
The website also features jihadist video footage and legal experts have warned the website could have breached laws on inciting terrorism.
'If the prison authorities claim they are monitoring and censoring material, then they are clearly not doing it effectively.'Labour MP Steve McCabe, who sits on the Commons home affairs committee, said: "Some of this stuff sounds dangerously close to incitement.
The website was taken down after the newspaper contacted Muhid - but a single homepage remains and features and email address fro people to send their letters, and quotes from the Qur'an.
Muhid denies glorifying terrorism, has offered to take down anything amounting to incitement and stressed inmates' letters had to be screened by prison authorities.
He said he did not intend to break the law, and added: 'Our role is to connect prisoners with the outside world...increasing the morale of these people.'
But Muhid admitted a disproportionate number of letters were sent to inmates with terrorism links and said the only just law is Islamic law.
A Ministry of Justice (MoJ) source said prisoners were not able to contribute directly to websites and that the department was aware of it.
An MoJ spokesman said: "The National Offender Management Service (Noms) recognises the risks posed by extremist offenders and those who seek to radicalise others and takes their responsibility to effectively manage these risks seriously.
"Since 2007 a dedicated, expert unit has led a programme of work across prisons and probation to strengthen our response to the threat from these offenders, drawing on our long history of managing terrorist prisoners and other dangerous individuals.
"All high-security establishments have a dedicated counter-terrorism unit, and a national unit also exists to analyse intelligence from the High Security Estate.
'Noms' response to the current threat has included staff training in extremism awareness, the ongoing development of interventions designed to assist offenders in disengagement from extremism and the strengthening of the role of the Muslim chaplain in prisons.'
