PM Brown: Public spaces need better protection against car bombs

Britain unveiled plans Wednesday to tighten defenses against car bombs at British airports and rail stations, as the country's terrorism minister warned of a 30-year battle against extremists. Prime Minister Gordon Brown said airports and 250 of the busiest train terminals would get new blast barriers and impose strict limits on access for vehicles. Brown did not elaborate on how access might be limited - or how that might affect passengers who already put up with what many call overcrowding and poor service at Heathrow International Airport in London. But in the past, Britain has erected security barriers around major buildings, and taken steps such as eliminating garbage cans to prevent them from being used as bomb receptacles.
