In a statement, the Turkish Defense Ministry said its warplanes destroyed 20 PKK targets including caves, bunkers, shelters and warehouses in the regions of Metina, Hakurk, Kandil, and Gara.
“Many terrorists were neutralized by using the maximum amount of domestic and national ammunition,” said the statement, which cited self-defense rights from Article 51 of the United Nations Charter to justify the strikes.
The PKK, which is classified as a terrorist organization by Turkey, the United States, and the European Union, earlier said it was behind the blast Sunday outside Turkey’s Interior Ministry building that left one dead and two injured, the pro-PKK Firat News Agency reported.
The ministry said in a statement that two attackers murdered a civilian and stole his vehicle ahead of the opening of parliament in Ankara. Two police officers reportedly received non-life-threatening injuries.
One assailant blew himself up and the other was “neutralized,” the ministry said.
Investigators found four different types of guns, three hand grenades, one rocket launcher, and C-4 explosives at the scene.
The ministry confirmed at least one of the two attackers is a PKK member. The second attacker has yet to be identified, it said.
Kurds, who do not have an official homeland or country, are the biggest minority in Turkey, making up between 15% and 20% of the population, according to Minority Rights Group International.
Portions of Kurdistan – a non-governmental region and one of the largest stateless nations in the world – are recognized by Iran, where the province of Kordestan lies; and Iraq, site of the northern autonomous region known as Kurdistan Regional Government (KRG) or Iraqi Kurdistan.
According to Ankara, the PKK trains separatist fighters and launches attacks against Turkey from its bases in northern Iraq and Syria, where a PKK-affiliated Kurdish group controls large swaths of territory.
Terror attacks in Turkey were tragically common in the mid to late 2010s, when the insecurity from war-torn Syria crept north above the two countries’ shared border.
And in November last year, Ankara blamed the PKK for a bomb attack on a central pedestrian boulevard in Istanbul that killed six and injured dozens.
In recent years, Turkey has carried out a steady stream of operations against the PKK domestically as well as cross-border operations into Syria.
In an address to lawmakers Sunday, Turkish President Recep Tayyip Erdogan vowed that Turkey would continue its fight against terrorism “until the last terrorist is eliminated domestically and abroad.”
Sunday’s attack marked the “final flutters of terrorism” in the country, he added.
