ISIS

We all know who ISIS is. They are originally named as the Islamic State. They represent the terrorist attacks in city's like Barcelona, Paris and Berlin.

According to the article the author says "Raqqa, ISIS 'Capital; Is Captured, U.S-Backed Forces Say"

American-backed forces said on Tuesday that they had seized the northern Syrian city of Raqqa from the Islamic State, a major blow to the militant group, which had long used the city as the 'de facto' capital of its self declared 'caliphate'.

The United States Central Command stopped short of declaring victory, saying that more than 90 percent of Raqqa is in S.D.F. control, a reference to the Syrian Democratic Forces, an American-backed militia group made up of Syrian Kurds and Arabs.

The article also says: Another major concern, now that Islamic State-held territory is reduced, is how countries in Europe, in the Middle East and around the world will handle the foreigners who joined the group in places like Syria and might return home and plan attacks there.
