Boston explosion

Two simultaneous explosions ripped through the crowd at the finish line of the Boston Marathon on Monday, killing at least two people and injuring dozens on a day when tens of thousands of people pack the streets to watch the world famous race. Russians responded to the attack immediately. They brought flowers to the U.S. Embassy in Moscow, while the authorities made an attempt to find out who was behind the terrorist attack.
