Turkish police on Tuesday detained 10 senior officials of district municipalities in Istanbul over their alleged links to Kurdish militants, the state-run Anadolu Agency reported, widening a crackdown on opposition-held districts in the city.

The detainees include the deputy mayors of the districts of Kartal and Atasehir, along with eight district municipal council members, Anadolu reported. All suspects are members of Turkey's main opposition Republican People's Party, or CHP.
