The incident took place near a building used by riot police and came hours after authorities detained at least 12 pro-Kurdish legislators from the People’s Democratic Party, or HDP, for questioning in terror-related probes. The formal arrests, which come a day after nine co-leaders of the pro-Kurdish opposition Peoples’ Democratic Party (HDP) were jailed pending trial, are likely to spark more concern among Turkey’s allies about President Recep Tayyip Erdogan’s intolerance of dissent in the wake of a failed July 15 coup. European Union foreign policy chief Federica Mogherini said she was “extremely worried” by the arrests, and raised her concerns in a telephone call with Turkey’s foreign and EU affairs ministers late on Friday. Southeastern Turkey has been rocked by political turmoil and violence for more than a year after the collapse of a ceasefire with the Kurdistan Workers Party (PKK) militant group, which has waged a three-decade insurgency for Kurdish autonomy. Meanwhile, watchdog groups in Turkey report a crackdown on Internet freedoms, the AP writes:

"The TurkeyBlocks monitoring network is reporting that access to various social media and messaging apps have been restricted as of 1:20 a.m. Friday, coinciding with the detentions of 12 pro-Kurdish politicians. Selahattin Demirtas and Figen Yuksekdag, the co-chairs of the pro-Kurdish People's Democratic Party, were among those rounded up in the middle of the night. An Istanbul court on Saturday ordered the formal arrest of nine employees of the opposition Cumhuriyet newspaper, widening Turkey’s crackdown on dissenting voices.
