At 3:36pm local time on July 22, a bomb exploded near the government's headquarters in Oslo, Norway. Seven people were confirmed killed, and many others injured. Two hours later, a gunman disguised as a police officer opened fire at a youth camp, and up to 80 people have reportedly been killed. The gunman, described as a 32-year-old Norwegian, was arrested; he was seen in Oslo shortly before the bomb blast. Norway is still reeling from the most devastating terror attack in its history.
