A suicide bomber thought to have crossed recently from Syria killed at least 10 people, most of them German tourists, in Istanbul's historic heart on Tuesday. Nathan Frandino reports.
The victims of Tuesday's suicide bombing in Istanbul were foreigners -- most of them tourists from Germany. German Chancellor Angela Merkel confirmed the news in Berlin. (SOUNDBITE) (German) GERMAN CHANCELLOR ANGELA MERKEL SAYING: "After hours of great worry, we have come to know that sadly, according to the Turkish government, at least eight of the people who were killed today in Istanbul were German." One Peruvian national was also killed. The tourists were all visiting Sultanahmet Square, near the Blue Mosque and Hagia Sophia, when the bomb went off. At least a dozen were wounded. There was no immediate claim of responsibility, though Prime Minister Ahmet Davutoglu blames Islamic State. Turkey is part of the U.S.-led coalition fighting the group...also known in Arabic as Daesh. (SOUNDBITE) (Turkish) TURKISH PRIME MINISTER, AHMET DAVUTOGLU, SAYING: "Our fight against Daesh, who carried out this attack, will continue with determination. We will not take a step back in our fight against Daesh. Our resolve will continue as in our fight against all terrorist organizations." Officials say the suspect was believed to have recently entered Turkey from Syria.
