The most senior Islamic cleric in Birmingham claimed yesterday that Muslims were being unjustly blamed in the war on terrorism and that the eight suspects in the two bombing attacks on London "could have been innocent passengers".

Mohammad Naseem, the chairman of the city's central mosque, called Tony Blair a "liar" and "unreliable witness" and questioned whether CCTV footage issued of the suspected bombers was of the perpetrators.

He said that Muslims "all over the world have never heard of an organisation called al-Qa'eda".

Mr Naseem, who was speaking after police seized Yasin Hassan Omar in Birmingham, delivered his unprompted outburst when he was invited to a press conference with West Midlands police and Birmingham city council to help calm fears of racial or religious tension after the arrest.

It was held near the police cordon in Heybarnes Road, where Omar was arrested.
