FRANKFURT—German police said they were holding a 26-year-old Syrian man in custody on Sunday after a knife attack in the city of Solingen in which three people were killed and eight injured, adding that they were looking into the suspect’s possible links with the ISIS terrorist group.
The attack occurred during a festival on Friday evening in a market square where live bands were playing to celebrate Solingen’s 650-year history. Mourners made a makeshift memorial near the scene.
