Turkish prosecutors issued warrants Friday for the detention of 82 people over 2014 protests about the siege by Islamic State of the Syrian Kurdish town of Kobani.

Those targeted included members of the pro-Kurdish Peoples Democratic Party (HDP) opposition party,

At least 18 of the suspects were detained during police raids in seven provinces, Anadolu Agency reported.

The suspects include Ayhan Bilgen, the current mayor of the eastern city of Kars, six former HDP lawmakers, and other former party executives, the agency said.

What were the Kobani protests?

Protesters took to the streets in Turkey's mainly Kurdish southeast in early October 2014, angered at what they perceived to be the government's inaction against Islamic State militants who had besieged Kobani.

The three days of protests left 37 people dead and hundreds injured.

It was not immediately clear why the investigation against the 82 people was launched six years after the rioting.
