Six British Muslim men were jailed on Friday after being found guilty of supporting terrorism in speeches made at a London mosque.
Among them was Omar Brooks, also known as Abu Izzadeen, an outspoken Muslim activist who leapt to public attention in 2006 when he heckled then Home Secretary John Reid in front of television cameras.
Brooks and Muslim convert Simon Keeler were both jailed for four and a half years at Kingston Crown Court for inciting terrorism overseas and terrorist fundraising.
"These are extremely serious offences," said John McDowall, head of the Metropolitan Police Service's Counter Terrorism Command.
"The overwhelming majority of people totally reject the deeply offensive views peddled by these defendants. They deliberately set out to incite people to carry out terrorist acts."
The charges arose from speeches, and preaching the men were involved in, at London's Regents Park Mosque on November 9th, 2004 in which they called on people to fight British and American forces in Iraq and to donate money to fund terrorism.
Officers discovered video tapes of some of the speeches during searches of a property following protests in central London in February 2006 over the publication of cartoons of the Prophet Mohammad in Danish newspapers.
All six were found guilty on Thursday, following a three-month trial.
