鈥� A daily summary of global reports on security issues.

Organizers of the London Marathon, the world's next major marathon, are reviewing their security measures but promise that the race this Sunday will go on, despite concerns over the attacks on the Boston event, which left at least three people dead and 130 people injured.

Chief Superintendent Julia Pendry, the Metropolitan Police officer in charge of the London Marathon's security, told the BBC that "We will be reviewing our security arrangements in partnership with London Marathon." And London Marathon chief executive Nick Bitel told the BBC that .

He said security plans "take account of many contingencies, including this type of threat and incident, but one can't be complacent and when it has happened, you need to then review those plans you have in place to see what else may be necessary."

UK Sports Minister Hugh Robertson, noting that London has experience with major sporting events, including the 2012 Olympics, said that "This is one of those instances where the best way to show solidarity with Boston is to continue."

The two Boston bombs, which exploded four hours and nine minutes into the marathon and 12 seconds apart, , wounding scores of race watchers and blowing out windows within yards of the finish line. The Boston Globe reports that officials called the investigation of the attack "very active and fluid." No one is yet in custody in connection with the attack, and no suspects have been named or claimed responsibility, 海角大神 reported.聽

The city has , closing off a mile-long, three-block-wide swath of Boston's Back Bay area, centered on Copley Square, while investigators scour the area for evidence.

The Boston Marathon explosions around the globe, the Globe notes. And marathons pose a particularly large challenge, because they sprawl across cities and towns along open roads.

鈥淚鈥檝e lost sleep over the fact that you have 52 miles of open roadway, 26 on each side,鈥� said Guy Morse, who served as Boston Marathon race director from 1985-2000 and BAA executive director from 2000-2010. 鈥淭hat鈥檚 the way I looked at it. You look at both sides of the road, as well as the course itself. It is impossible to secure it to the extent necessary. So, it has significant ramifications for major events.

鈥淔rom the Olympics on down, we鈥檙e all in the same mode of providing as effective a security net as we can for runners and spectators.鈥�

Mr. Morse worries that increasing security around marathons could undermine the characteristics that give them such an appeal.

鈥淥ne of many things it could mean is that the public is pushed even further back,鈥� said Morse. 鈥淏ut I don鈥檛 want to think about a scenario where you finish marathons in a stadium where no one can get in. This sport is much about the spectators as well as the athletes. It鈥檚 a relationship that鈥檚 important to the marathon world and marathoning.鈥�

The Associated Press reports that Olympic organizers of the 2016 Games , and said they "are working very closely with our government partners to deliver safe games in 2016." World Cup organizers in Brazil, which will also host the 2014 soccer tournament, did not comment on the Boston attack.
