Turkish President Recep Tayyip Erdogan has visited the site of the recent explosion in Istanbul's Fatih district following his Friday prayer at the famous Sultan Ahmet Mosque (Blue Mosque).
Erdogan made a statement to the press after he laid carnations in order to pay his respects to the victims of the bombing.
Erdogan, who stood in front of the explosion site, pointed out that Turkey has currently been fighting against several terrorist organisations including PKK, YPG, and DAESH operating in its respective region.
A recent suicide attack reportedly carried out by a DAESH terrorist took place in Istanbul's Fatih district, killing 10 German tourists and wounding 15 mostly foreign tourists last Tuesday.
"There have been 10 [terrorist] acts by DAESH against Turkey so far. Our combat against any terrorist organisation, especially PKK and DAESH, will continue resolutely," Erdogan told reporters.
Erdogan also said that the attack was being investigated in a multi-directional way.
"The presence of DAESH in Turkey is not acceptable," he added.
Turkish high-ranking officials previously stated that the suicide bomber was a Syrian citizen who was born in Saudi Arabia in 1988 according to an official investigation.
Turkey has recently faced violent attacks by various groups including the PKK, DHKP-C and DAESH terrorist organisations.
DAESH terror attacks have reportedly killed more than 100 civilians in Turkey in 2015.
In October 2015, 103 people were killed in a twin DAESH suicide bomb attack in Turkey's capital Ankara while in another DAESH suicide bombing 34 people were killed in the Suruc district of Turkey's southeastern Sanliurfa Province, which borders Syria, on July 20, 2015.
