Turkish and German politicians called for calm on Wednesday after a fire in Germany which killed nine people of Turkish origin stoked tension. Speculation that Sunday's blaze was a racially motivated crime has mounted and the case threatens to overshadow a visit to Germany by Erdogan. REUTERS/Kai Pfaffenbach(GERMANY)
