Turkish fighter jets  bombarded positions of the outlawed Kurdistan Workers’ Party (PKK) following militant attacks on military outposts in southeastern Turkey.

The Turkish General Staff ordered the bombing of the PKK’s positions in the Daglica district in the southeastern Hakkari province Monday, Hurriyet news reported.

The bombarded targets were reportedly involved in “assassination, armed incidents and attacks on security bases” after last week’s nationwide protests.

Many provinces in east Turkey, as well as the largest cities of the country, saw violent protests against the government’s policies over the Islamic State’s (IS) advance on the Syrian border town of Kobane.

Some 37 people were killed and hundreds were injured in the demonstrations.

The Daglica military guard post was attacked with rocket-propelled grenades by the PKK for three days, and the Turkish military airstrikes came after the last attack that took place Monday.

Turkey’s F-16 and F-4 jets flying from Malatya and Diyarbakir bombarded the positions.

The airstrike is the first broad operation against the PKK since 2013 when the organisation accepted a ceasefire and began withdrawing its fighters to the Kurdistan region in northern Iraq.

The PKK is a militant organisation formed in 1978 by a group of radical Kurdish students led by Abdullah Öcalan.
