Turkey arrested three German citizens of Lebanese origins, suspected of having links to the slain perpetrator of an ISIS attack on a Christmas market in Berlin last year, the Interior Ministry said on Monday.

Police detained the three men identified as Mohammad Ali Khan, Youssef Darwiche and Bilal Yosef Mahmoud, at Istanbul’s Ataturk Airport upon intelligence that they would try to go to Europe, according to Turkish daily Hurriyet

The three are believed to have been involved in the attack that took place on December 19, when Tunisian national Anis Ameri plowed a truck into a crowded Christmas market in Berlin, killing 12 and wounding 49.

ISIS claimed the attack a day later, and 24-year-old Ameri fled to Milan, where he was shot by police.
