Seven suspected DAESH terrorists were remanded into custody after a court appearance in Ankara on Wednesday, Turkish judicial sources reported.
The suspects, along with five others, had been detained on Monday during an early morning operation in the Ulus neighbourhood.
The other suspects were released on condition of judicial control.
Turkey has increased its security operations against DAESH, after the group reportedly killed a non-commissioned Turkish military officer who was on duty at the border post in the Elbeyli district of Kilis in July 2015.
DAESH terror attacks have killed nearly 150 civilians in Turkey since July 2015.
In October 2015, 103 people were killed in a twin DAESH suicide bomb attack in Turkey's capital Ankara. On July, 20, 2015 another DAESH suicide bombing had resulted in the death of 34 people in Suruc district of Turkey's southeastern Sanliurfa province, which borders Syria.
A recent suicide attack determined to be carried out by a DAESH terrorist, took place in Istanbul's Fatih District, killing 11 German tourists and wounding 15 -mostly foreign- tourists on Jan. 12, 2016.
Following the attack, Turkish tanks and artillery heavily bombarded DAESH positions in Syria and Iraq, leading to the death of at least 200 terrorists, according to Turkish Prime Minister Ahmet Davutoglu.
