BOSTON MARATHON

Every year in April, the Boston Marathon brings together more than 30,000 runners. The names of the winners are engraved on a plaque fixed to the ground in Copley Square. The event was marked by the 2013 attacks: during the 117th edition of the Boston Marathon, two bombs exploded within seconds of each other near the finish line, on Boylsont Street. Three people were killed and 264 were injured. Three days later, the main culprits were identified by the FBI. They were the Tsarnaev brothers, American citizens from Chechnya.
