British Prime Minister Tony Blair says Muslim leaders must confront what he called the "evil ideology" present in Britain's Islamic community.
Following a meeting with leaders of the country's Muslim Council Tuesday, Mr. Blair said council members agreed with him of the need to have people go into the Muslim community and address the conditions that convinced four young men to bomb London's transit system.
In a related development, authorities in Cairo have cleared an Egyptian biochemist wanted by Britain for questioning in relation to the attacks. They say Magdy el-Nashar has no connection to either the transit bombings or the al-Qaida terrorist group.
Egyptian police arrested Mr. el-Nashar in Cairo last week. He had been living in the same city in northern England that had been home to three of the suspected suicide bombers.
British officials say they found traces of explosives in his home in Leeds.
