SOLINGEN, Germany: German Chancellor Olaf Scholz said Monday the government would tighten weapons controls and speed up deportations after a suspected Islamist knife attack in the western city of Solingen. Friday night’s deadly stabbing at a street festival has reignited a debate over immigration in the country and put extra pressure on Scholz ahead of key regional elections set for Sunday. “This was terrorism, terrorism against us all,” Scholz said on a visit to Solingen, where he laid flowers at a memorial to the victims.
