A suicide bomber who killed himself and 10 German tourists in Istanbul's historic heart had registered with Turkish immigration authorities but was not on any list of known militant suspects, Turkey's interior minister said on Wednesday. The bomber, a Daesh member thought to have come recently from Syria, blew himself up on Tuesday in Sultanahmet square near the Blue Mosque and Hagia Sophia, major tourist sites in one of the world's most visited cities. Asked about a report in the Turkish media that the bomber had registered at an immigration office in Istanbul a week ago, Interior Minister Efkan Ala confirmed that the man's fingerprints were on record with the Turkish authorities. "Your assessment that his fingerprints were taken and there is a record of him is correct. But he was not on the wanted individuals list. And neither is he on the target individuals list sent to us by other countries," Ala told a joint news conference with his German counterpart Thomas de Maiziere. Turkey's Haberturk newspaper published what it said was a CCTV image of the bomber, identified in some local media reports as Nabil Fadli, at an immigration office in Istanbul on Jan. 5. It said he was identified by a sample of a finger taken from the blast site. Deputy Prime Minister Numan Kurtulmus said on Tuesday the bomber had been identified from body parts at the scene, was born in 1988, and was thought to have been living in Syria, from where he was believed to have recently entered Turkey. Ten Germans were killed in the bombing, a spokeswoman for the German foreign ministry said, raising the death toll among Germans from 9 previously. Foreign tourists and Turks paid their respects at the site early on Wednesday. Scarves with the Bayern Munich football club emblem were left along with carnations and roses at the scene, before Turkish police sealed off the area. De Maiziere said there were no indications Germans had been deliberately targeted and that he saw no reason for people to change travel plans to Turkey. He said Germany stood resolutely by Turkey's side in the fight against terrorism. "If the terrorists aimed to disturb, destroy or jeopardize cooperation between partners, they achieved the opposite. Germany and Turkey are becoming even closer," he said. "Based on what we know from the investigation so far, there are no indications that the attack was explicitly targeting Germans so there cannot be a link with our contribution to the fight against international terrorism," he said. The guide of the German group was quoted by Turkey's Hurriyet newspaper as saying she had yelled "run" after seeing the bomber, who was standing among the tourists, pull a pin on his explosives, enabling some of them to get away. Ala said nine other Germans were wounded in the blast, two of them still in a serious condition in hospital, along with one Norwegian and one Peruvian. He vowed to work closely with Germany in investigating the attack. One person was detained late on Tuesday as part of the investigation into the blast, Ala said, but gave no details.
