Turkey's interior minister has identified a key ISIS suspect captured by the country's forces in Syria as the alleged mastermind behind attacks in Russia and Germany, according to a newspaper report on Friday.

Turkey had announced last week that it detained an "important" ISIS figure but did not name him. In an interview published in Hurriyet newspaper, Suleyman Soylu identified the man as Yusuf Huba, describing him as a high-ranking ISIS member. Soylu said the man allegedly planned and ordered a bomb attack in Russia in 2018 as well as an attack at a supermarket in Germany.

Turkey has been highlighting what it says is its fight against ISIS, in the face of accusations that the Turkish military offensive last month to drive Syrian Kurdish fighters from northeast Syria would allow for a resurgence of the militant group.

The interior minister said the suspect is also known as Abu Jihad al-Din al-Nasir Ubeyde and is being held and questioned in Syria, in an area controlled by Turkey.

"We have captured a very senior ISIS member who is known as a bomber, bomb-maker, and mastermind of suicide bomb attacks," he told Hurriyet.

It was not clear which attack in Russia in 2018 the minister was referring to. In a 2017 attack in the northern German port city of Hamburg, a 26-year-old Palestinian man killed one person and wounded six others in a stabbing spree at a supermarket.

Since its military incursion into Syria, Turkey has been deporting foreign ISIS members who are held in Turkish prisons or in Syria to their home countries. ISIS suspects from the United States, Denmark, Germany and the Netherlands have been repatriated in the past two weeks. Turkey also plans to soon deport an Irish woman and her child as well as 11 French nationals.
