Armed gunmen opened fire late Jan. 27 on the municipal building of ÅiÅli, one of the most vibrant and central districts on IstanbulÂs European side. The attack caused no casualties, police said, although the assault seemed to target Mustafa Sarıgül, the Republican PeopleÂs PartyÂs (CHP) candidate for Istanbul mayor and the current mayor of ÅiÅli, ahead of the March 30 local elections.
