CNN  — 

As ISIS awaits one major assault in Mosul, Iraq, the self-declared caliphate has lost its control of a symbolic stronghold in north Syria.

The Free Syrian Army, a Turkish-backed faction, on Sunday took back the town of Dabiq from ISIS, Turkish state media and a monitoring group said.

The Syrian Observatory for Human Rights, a UK-based organization, said it received reports that groups of ISIS fighters had withdrawn from Dabiq overnight.

Though ISIS forces left, Turkish security sources told Anadolu’s reporter the recapture of Dabiq was the hardest part so far for Operation Euphrates Shield.

US Secretary of Defense Ash Carter welcomed news of the recapture of the town and congratulated the fighters involved. “This is more than just the latest military result against this barbaric group,” Carter said in a statement. “Dabiq held symbolic importance to ISIL. The group carried out unspeakable atrocities in Dabiq … and claimed it would be the site of a final victory for the so-called caliphate. Instead its liberation gives the campaign to deliver ISIL a lasting defeat.”

Now the Free Syrian Army operation will continue, according to Turkey’s state-run Anadolu, as fighters seek to clear the town of mines, booby-traps and IEDs.

The small city, which is about 10 kilometers (just over 6 miles) south of the Turkish-Syrian border, is considered by some Islamic prophecies to be the site of an apocalyptic battle between Christians and Muslims. ISIS has even named its sleek English language magazine, used to prominently feature propaganda, “Dabiq.”
