Members of the U.S. House of Representatives held a moment of silence Monday night (April 15) to remember victims of explosions at the finish line of theBoston Marathon.
Two explosions ripped through the crowd at the finish line on Monday, killing two people and injuring dozens on a day when tens of thousands of people pack the streets to watch the world famous race.
Runners were heading for the finish when a fireball and smoke rose from behind cheering spectators and a row of flags representing the countries of participants, video from the scene showed. Other pictures showed blood stains on the ground and several people knocked down.
An hour after the 2:50 p.m. EDT (1850 GMT) blasts in Boston's Copley Square marred the usually joyous end to the marathon, a fire erupted at the John F. Kennedy Presidential Library three miles (5 km) away, but no one was injured, police said.
Boston Police Commissioner Ed Davis told a news conference the authorities were not certain whether the fire, possibly started by an incendiary device, was related.
