Britain has detained ten foreigners deemed to pose a threat to national security. They are to be expelled under measures outlined last week to boot out radicals believed to be inciting or glorifying terrorism.One of those held was reportedly Abu Qatada. Described by officials as Osama bin Laden’s “spiritual ambassador in Europe”, the Jordanian cleric has lived in England since 1993. In a separate development, 10 people have appeared before magistrates in connection with the attempted bombings of July 21 in London. All are accused of failing to disclose information about a terrorism suspect. Three are also charged with assisting a person in evading arrest. The four men whom police suspect tried to plant the bombs have been detained. Three of them are being held in the UK, the fourth in Italy. The botched attacks came two weeks after suicide bombers killed 52 people on London’s public transport system.
