President Recep Tayyip Erdoğan said on Friday that attacks on places of worship stemed from the same "dark source".
Speaking at the inauguration ceremony of the Çamlıca Mosque complex, the largest mosque of Turkey, Erdoğan said he is "determined to clear the nation and region of Daesh, PKK, FETO, Al Qaeda terrorists".
"Attacks in the name of religion on places of worship or innocent civilians constitute terrorism, not jihad," said Erdoğan.
The 63,000-capacity mosque on Istanbul's Çamlıca Hill in the Asian side of the city was opened by Erdoğan for Friday prayer.
Built in the Ottoman-Seljuk style of architecture, the mosque can be easily viewed from every corner of the city.
