Just four months after the well-orchestrated attacks killed 130 people in Paris, ISIS has struck Europe again. This time, the radical Islamic group's target was the beautiful city of Brussels in Belgium. The first explosions rocked the Brussels Airport on Tuesday, March 22 at 8 am local time. The simultaneous attacks, both caused by suicide bombers, occurred close to airline check-in gates and outside security checkpoints for ticketed passengers. According to initial estimates, 11 people lost their lives, while 100 more were injured.
