FRANKFURT   -  A suspect in German police custody following a stabbing rampage in the city of Solingen that killed three people and injured eight is a 26-year-old Syrian man, authorities said on Sunday as they looked into his possible links with Islamic State. The incident, along with the militant group’s claim of responsibility, sparked concern among some politicians who urged enhanced security, tighter curbs on weapons, stiffer punishment for violent crimes, and limits to immigration. 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. The suspect turned himself in late on Saturday and admitted to the crime, Duesseldorf police and prosecutors said in a joint statement early on Sunday. German federal prosecutors identified the Syrian man as Issa Al H., omitting his family name because of German privacy laws, and said he was suspected of being a member of Islamic State. Prosecutors said “due to his radical Islamist convictions” he tried to kill as many people as possible that he considered to be non-believers, stabbing them repeatedly in the neck and upper body. Friedrich Merz, a prominent politician who leads the opposition, centre-right CDU party, said the country should stop admitting further refugees from Syria and Afghanistan.

“It’s enough!” he said in a letter on his website.
