Here is a clip from a newspaper.
The airstrikes - which employed U.S. Tomahawk missiles, B1 bombers, F16, F18 and F22 strike fighters and drones - was backed by support from Saudi Arabia, Bahrain, Qatar, Jordan and the UAE - a coalition of nations that has agreed to assist with the destruction of ISIS.
If IS is supported by Saudi Arabia - why are they bombing them.
