The United States and several Arab nations rained bombs on ISIS targets in
Syria on Tuesday -- the first U.S. military offensive in the war-torn country
and a forceful message to the militant group that the U.S. would not stand by
idly while it carried out its rampage of terror.
The
airstrikes focused on the city of Raqqa , the
declared capital of ISIS ' self-proclaimed
Islamic State. But other areas were hit as well.
The
operation began with a flurry of Tomahawk missiles launched from the sea,
followed by attacks from bomber and fighter aircraft, a senior U.S. military
official told CNN.
