Last weekend, French President François Hollande declared war on the Islamic State in Iraq and Syria (ISIS), the terrorist group that has taken responsibility for the brutal attacks in Paris, Beirut, and Baghdad last week.

ISIS has also claimed responsibility for downing a Russian airliner in Egypt earlier this month, killing 224 people.
