An Infernal Device

An Islamist fanatic detonated a bomb on a London underground train injuring more than twenty innocent people earlier today. This device was meant to kill with the hope that even more would die, trampled in a stampede to escape the tube. This type of attack is difficult to prevent, but thankfully, intelligence agencies have intercepted several similar efforts. Vigilance on the part of the public also helps. It is the infernal notion that killing innocents advances a religious agenda that must be defeated.
