London examines security

Safety Protocols And Challenges
LONDON -- British police are reviewing security plans for Sunday's London Marathon, the next major international marathon, because of the bombs that killed two people at the race in Boston. But there is no known specific or credible threat against the hugely popular British race at the moment, a security official said Monday.
Police already were preparing a major security operation for Wednesday's ceremonial funeral for former Prime Minister Margaret Thatcher, an event at St. Paul's Cathedral that will be attended by Queen Elizabeth II and many dignitaries. The plans call for a procession through the streets of London, with Thatcher's flag-draped coffin to be carried on a horse-drawn carriage.
The funeral's security plans are expected to be reviewed in light of the Boston bombings.
Other prominent marathon cities released statements sending their support to Boston.
From New York Road Runners president Mary Wittenberg: "All of our thoughts and prayers are with the victims and their families of the bombings at the Boston Marathon today, as well as with the runners, spectators, volunteers and staff of the Boston Athletic Association (BAA). Marathons bring out the best of the human spirit and unite our cities and towns.
"This is a tragic day for all of us in the running community. We are here in full support of our close friends at the BAA. The safety and security of all New York Road Runners' races is and will always be our top priority. We will continue to work hand in hand with the City of New York and the NYPD as we plan for upcoming events."
Organizers of the Chicago Marathon said: "We are deeply saddened by today's events, and our focus is on the victims and their families."
London has long been considered a top target for international terrorists, with the government saying the threat level is "substantial." In 2005, a series of suicide attacks on the public transport system in the British capital killed 52 people. London and mainland Britain also face a moderate threat from Northern Ireland-related terrorism, according to the government.
Two bombs exploded near the finish of the Boston Marathon on Monday, killing at least three people and wounding more than 140 others, race organizers and police said. The situation sparked alarm bells in Britain, where a massive security operation was put in place last summer to protect the successful London Olympics.
Last year, some 37,500 athletes competed in the London Marathon, with many more watching the springtime event.
Chief Superintendent Julia Pendry, police commander for the London race, said Monday that "a security plan is in place for the London Marathon. We will be reviewing security arrangements in partnership with (the) London Marathon."
A police spokesman who spoke on condition of anonymity because he was not authorized to go on the record said the security presence may be increased.
A security official, speaking on condition of anonymity because he was not authorized to speak publicly about the matter, said there are no credible or specific threats against the London Marathon.
The London race's chief executive, Nick Bitel, said marathon officials contacted the police to discuss security plans "as soon as we heard the news" about Boston. He expressed shock and sadness about the situation in Boston, saying "it is a very sad day for athletics and for our friends in marathon running."
