After September 11

Two explosions occurred at the finish line of the Boston marathon. According to the latest data, three people were killed and more than 140 were injured. Among the dead is an eight-year-old boy. This is the largest terrorist attack in the United States since September 11, 2001.

Two explosive devices were located close to each other, in crowded areas. In addition, police found five more explosive devices in the vicinity and defused them on the spot. The bombs may have been detonated remotely using mobile phones. The explosive devices were most likely made by hand. According to sources in law enforcement agencies, the terrorist attack was intended primarily not to kill, but to injure a large number of people. There has been speculation about the involvement of Islamic militants or American extremists opposed to the government.
