High-level Turkish officials speaking anonymously have claimed that Turkish security and intelligence organizations are dealing heavy blows to Islamic State cells and networks in the country.

The Turks have been rounding up foreign fighters who, according to their security organizations were plotting further terrorist attacks inside the country.

Since the New Year’s attack by IS in Istanbul which took 39 lives, Turkey has been dealing heavy blows to this extremist organization,” the official said. “Turkey is part of the international anti-IS coalition. We are very determined as always and continue to fight against IS and all other terrorist organizations.”

Last week, Turkish security forces stormed a suspected IS cell in the Anatolian province of Konya, killing at least five IS fighters.
