HANAU, Germany (AP) — Hundreds of grieving people are flocking to Friday prayers in the mosques of the German town of Hanau, two days after a racially motivated shooting. Germany’s top security official says authorities will step up the police presence throughout the country and keep a closer watch on mosques and other sites. A 43-year-old German man shot dead nine people of immigrant backgrounds in the Frankfurt suburb of Hanau on Wednesday night before killing his mother and himself. He left a number of rambling texts and videos espousing racist views. Calls for authorities to crack down on far-right extremism have grown.
