In the aftermath of Boston's bombings Sunday, London marathoners showed solidarity with 30 seconds of silence at the start of their 26-mile run through the city. Many of the thousands of spectators lining the streets were wearing black ribbons to commemorate the three dead and 170 injured in Monday's Boston Marathon bombing. The race was also marked with a 40 percent higher police presence than at last year's race. Barbara Stephenson, Charge d'Affaires at the U.S. Embassy said the commemoration underscored the "special relationship" between the two cities. "We've had responses from Her Majesty the Queen, all through Twitter from the British people, and now we have got tens of thousands of London Marathon runners wearing a black ribbon in solidarity with the people of Boston," she said.
