After yesterday’s bombing in Boston, the world is on edge. Recent discoveries show that the bombs were made out of ordinary kitchen pressure cookers, packed with nails and other extremely sharp shrapnel. These bombs were hidden in duffel bags that were left on the ground towards the finish line of the Boston Marathon. President Barack Obama has stated that this was an act of terrorism, but he doesn’t know whether or not this was carried out by a solo bomber or a group of bombers. The FBI has vowed to “go to the ends of the Earth” to find out who’s responsible for such a horrendous act.
