An explosion occurred in Istanbul's Sultanahmet Square early on Tuesday, in which the city's governorate released a statement, saying that 10 were killed and 15 injured in the blast, while Deputy Prime Minister Numan Kurtulmuş said in a live TV press conference that the blast was done by a male Syrian suicide bomber born in 1988.Later in the day, Prime Minister Ahmet Davutoğlu held a live press conference, during which he said the assailant was a member of the Daesh terror organization.Davutoğlu said that everyone killed in the blast were foreign nationals, while Turkish citizens were among the wounded. "Until Daesh positions are eliminated from our border, Turkey will continue its anti-terror struggle," the prime minister said, adding that Syrian nationals living in Turkey should not be blamed for the attack.The suicide bomber was identified as Saudi Arabia born, Syrian citizen Nabil Fadli, some Turkish media outlets reported.Deputy PM Kurtulmuş spoke of the incident in an earlier press conferencewith Interior Minister Efkan Ala and Health Minister Mehmet Müezzinoğlu, after a security meeting was held at the chairmanship of Prime Minister Ahmet Davutoğlu at Çankaya Palace in the Turkish capital Ankara. Kurtulmuş told reporters that two of the injured were in critical condition. "The blast is an extension of proxy wars that have been going on in Syria for the last 5 years," he said, while asking all countries to stand beside Turkey in the fight against terrorism.Kurtulmuş stated that Turkey would continue its fight against terrorism and ensure security, adding the struggle against terrorism was not a fight a country alone can win. "So, we expect friends of Turkey, the international community to raise their voices against terror attacks targeting Turkey and show their solidarity. We should boost our fight against terrorism and it is obvious now that international cooperation is very important in anti-terrorism efforts," he said."Terrorists do not discriminate in their attacks, they kill civilians, men, women, the elderly and the youth. Terrorism does not have any religion, language or sect. Terrorists are enemies of humanity and we would like to see everyone on our side to confront the attacks against humanity," he said. "The civil war in Syria entered into a new phase with support of third parties seeking to boost their influence as regional and global powers, to numerous terrorist organizations. It is more brutal and merciless now. We have no doubt that the attack might be a reflection of the proxy war in Syria," he said, without singling out any countries. In a separate live conference later on in the day, Kurtulmuş said that the assailant was believed to be a new comer to Turkey from Syria, and was not among those already being followed by police.The Istanbul Governorate released a statement early in the morning just after the explosion, saying that the reason of the blast, type of the explosive, and perpetrator(s) were being investigated.Later on, the governorate said that six German nationals, one Norwegian citizen and a Peruvian national were among the injured, which was confirmed by the Peru's foreign ministry. The ministry said that one Peruvian killed, and one wounded in the bombing.A statement also came from Berlin regarding the attack, as Chancellor Angela Merkel and her Foreign Minister Frank-Walter Steinmeier said that German citizens are "probably" among the 10 killed in the blast.Sources in the Turkish Prime Minister's office also reportedly confirmed this, saying nine of those killed in the blast were German citizens.Davutoğlu has also touched upon this issue during Monday's live conference, saying he "would like to address our friend and ally Germany, and the pain of those killed is in hearts of 78 million [Turkish citizens]." The explosion took place near the Sultanahmet Tram station and Dikilitaş, the Obelisk of Theodosius, at around 10:20 a.m. local time.Local reports said the explosion could be heard from several neighborhoods of the city. Many ambulances and police units were dispatched to the scene of the explosion early in the morning, while the injured were transferred to local hospitals.
