The blast took place in the city’s Sultanahmet square, a major tourist attraction, claiming the lives of 10 German citizens and injuring 15 more from various nationalities on Tuesday.
Ankara claims that the attack was carried out by a member of the Daesh Takfiri terror group who had recently entered Turkey from Syria, although no group has claimed responsibly for the incident.
Turkey has been on high security alert since more than 100 people were killed in twin blasts in Ankara last October. The attack was blamed on Daesh terrorists.
Ankara has been among the main supporters of the militant groups operating in Syria since March 2011.
