Ankara said it had fired 500 times on the barbaric terror network’s militiamen, killing 200 jihadis.
The action was in retaliation after a suicide bomber murdered German holidaymakers in central Istanbul on Tuesday.

Talks will be held in the Turkish capital Ankara to secure closer work on tackling foreign fighters and cutting off funding for the jihadi group.
Turkey has been criticised internationally for being slow to react to the rise of IS, and its border has been a key crossing point for militants heading to fight for the extremists.
Foreign Secretary Philip Hammond said: "Turkey, a Nato ally, is a vital friend of the UK and critical partner in tackling Islamist extremism, as we have seen so tragically in Istanbul this week.
"I applaud Turkey's generosity in hosting over 2.5 million Syrian refugees. Britain will be stepping up its cooperation with Turkey in countering the scourge of Daesh and our efforts to deliver vital humanitarian and other support, inside Syria including to besieged towns.
"We will be discussing how we can work even more closely together in tackling the flow of foreign fighters and funding to Daesh; and how we can best support people displaced by the fighting in Syria - including through the London Syria Conference in February."
