(CNN) —  

Terrorist attacks hit three continents Friday – Europe, Africa and Asia. Many innocent people were killed

Suddenly it felt as if a war was on. The toll was stark, as CNN.com reported: A beheading in France. An attack on tourists in Tunisia. A bombing in Kuwait.

ISIS, the murderous group now rampaging through parts of the Middle East, has so far claimed responsibility for the Kuwait bombing. It is unknown whether all the attacks were the work of the same group.
