A suspect in the failed London bombings who was arrested in Birmingham will appear in court today accused of conspiracy to murder.

Yassin Omar is alleged to have tried to detonate a bomb on the Tube at Warren Street on July 21.

A spokesman for Scotland Yard said Omar was charged with conspiring with others to "murder passengers on the Transport for London system".

A second charge says he "unlawfully or maliciously made or had in his possession or under his control an explosive substance with intent by means thereof to endanger life or cause serious injury to property".

Omar was also charged with the attempted murder of passengers on the transport system and conspiring with others before July 21 to use explosives to endanger life.

The spokesman said Omar will appear today at Bow Street Magistrates Court, London. Omar, a 24-year-old Somalian, was arrested on July 27 after he was felled with a Taser gun when officers stormed the safehouse in Birmingham where he was hiding.

Meanwhile, the chairman of Birmingham's Central Mosque said Tony Blair's announcement of new measures to tackle Islamist radicalism was comparable to Adolf Hitler's demonisation of the Jews in pre-war Germany.

Dr Mohammed Naseem said the Prime Minister was "not very wise" to propose action against extremist Muslim preachers in the wake of the London terror attacks.

There have already been calls for Dr Naseem's resignation, after he questioned whether Muslims were responsible for the July 7 atrocities and suggested that al Qaida may not exist.

Dr Naseem said there were "similarities" between Mr Blair's approach to Britain's Muslim community and Hitler's demonisation of Jews early in his time as German Chancellor.

"He (Hitler) was democratically elected and gradually he created a bogey identity, that is, the Jewish people, and posed to the Germans that they were a threat to the country," said Dr Naseem.

"On that basis, he started a process of elimination of Jewish people. I see the similarities. Everything moves step by step. I am saying these are dangerous times and we must take note of this."

Dr Naseem said that the measures proposed by Mr Blair would be "appropriate" if there was evidence that foreign nationals were in the country fomenting terrorism.
