British police have arrested six people - five men and a woman - on suspicion of plotting an act of terrorism. The arrests, in Ealing in west London and in the east London district of Newham, forced the closure of a busy highway for hours on Thursday. However, authorities stressed that the arrests, which included three brothers and a married couple, were pre-planned and not linked to the Olympic Games which begin in London in three weeks. Andrew Simmons reports.
