Officials and reports say police in Turkey have detained a would-be Kurdish rebel suicide bomber and rounded up 12 suspected Islamic State militants as it presses ahead with a crackdown on terror groups.

The regional governor's office said police on Wednesday detained a militant of the Kurdistan Workers' Party, or PKK, who it claimed planned an attack in the majority Kurdish city of Diyarbakir.

The state-run Anadolu Agency reported, meanwhile, that police conducted raids in Ankara and three other cities, detaining at least 13 people suspected of links to Islamic State extremists.

Turkey has conducted airstrikes against PKK targets in Iraq and IS militants in Syria in the wake of a suicide bombing that killed 32 people in late July, while rounding up hundreds of suspected militants at home.
