ISTANBUL — Turkish police have arrested one person in connection with the deadly suicide bombing in Istanbul that killed 10 Germans, officials said Wednesday.

The suspect was detained in Istanbul late Tuesday, Interior Minister Efkan Ala said during a news conference with his visiting German counterpart. He didn’t provide further details. Turkish media reports said police had raided a home in an affluent neighborhood of Istanbul, detaining one woman suspected of having links to the Islamic State group, although it wasn’t clear if she was the suspect Ala was referring to.

On Wednesday, Turkish police also arrested 13 suspected IS militants, including three Russian nationals, a day after the bombing in Istanbul’s historic Sultanahmet district. The attack, which also wounded 15 other people, including Germans, a Norwegian man and a Peruvian woman, was the latest in a string of attacks by Islamic extremists targeting Westerners.

Turkish authorities identified the bomber as a Syrian born in 1988, who had recently entered Turkey. Turkish media, including newspapers close to the government, identified him as Nabil Fadli, and said he was born in Saudi Arabia. Ala said the suicide bomber wasn’t on any Turkish or international watch lists for IS militants.

Officials initially said that at least eight Germans were among the dead in Tuesday’s explosion. On Wednesday, German Foreign Ministry spokeswoman Sawsan Chebli said the number had risen to 10.

German Interior Minister Thomas de Maiziere said there was no sign that Germans were specifically targeted.

“According to the investigations so far, there are no indications that the attack was directed specifically against Germans, so there can’t be any connection to our contribution to the fight against international terrorism,” de Maiziere said.

Germany committed Tornado reconnaissance jets to the military effort against the Islamic State group in Syria following the November attacks in Paris, and started flying missions from the Incirlik air base in Turkey last week. It also sent a tanker aircraft, as well as a frigate to help protect a French aircraft carrier in the eastern Mediterranean. It hasn’t taken a direct combat role, however. Germany already was helping supply and train Kurdish forces fighting IS in northern Iraq.

Ala urged Turkish citizens and foreign visitors to go about their daily lives, insisting that the country had taken “all necessary security precautions.” He said Turkey had detained as many as 220 IS suspects in the week prior to the attack.

De Maiziere said: “I see no reason to refrain from traveling to Turkey.” He added there was no reason for people who are already there to break off their trips.

Top German and Turkish officials already were scheduled to meet in Berlin next week to discuss Europe’s migrant crisis, in which Turkey – which borders both Syria and the European Union – is a key player. De Maiziere said those talks will now also address “the determined fight against terrorism.”

“If the terrorists aimed to destroy or endanger the cooperation between partners, then they achieved the opposite,” de Maziere said. “Germany and Turkey are coming even closer together.”
