Azzam Tamimi, a director, has repeatedly expressed his belief that suicide bombings are martyrdom operations, and lead to paradise in the next life. Another director, Kathem Sawalha, was named as a co-conspirator in a 2003 indictment brought by US federal prosecutors in Chicago against Hamas activists in the US. According to the indictment, before Mr Sawalha moved to London in the early Nineties, he was a Hamas leader in the West Bank. Why are such men being allowed to organise and repeatedly address young Muslims in London?
