Clashes have erupted in southeast Turkey after a rally to mark 17 years since the arrest of Abdullah Ocalan, leader of the PKK, an outlawed Kurdish movement.

About 300 demonstrators assembled in the mainly Kurdish district of Diyarbakir chanting "We will win by resisting" and "long live Apo," in reference to Ocalan.

Police unleashed tear gas and water cannons to disperse the rally. Young men retaliated with stun grenades and fireworks.

The PKK — designated a terrorist organization also by the U.S. and the EU — renewed its armed campaign against the Turkish state in late July.

Turkish security forces have been engaged in large-scale operations against Kurdish militants since December, imposing controversial curfews in flashpoint areas and raising concerns over civilians caught up in the fighting.
