Turkish air forces have launched airstrikes on neighbouring Iraq and Syria in apparent retaliation for a deadly terrorist attack at a state-run aerospace manufacturer’s headquarters.

Turkey said it had destroyed 32 targets in northern Iraq and northern Syria, killing many members of the Kurdistan Workers’ Party (PKK) terrorist organisation.

No one has claimed responsibility for the attack at the Turkish Aerospace Industries building in Ankara on Thursday morning (AEDT), but the Turkish government is blaming PKK.

Defence Minister Yasar Guler said Turkey would pursue the militant group “until the last terrorist is eliminated”.

“We give these PKK scoundrels the punishment they deserve every time. But they never come to their senses,” he said.

PKK has a foothold in Iraq, while a Kurdish militia group in Syria is affiliated with the militants.

Two attackers armed with assault rifles killed five people and wounded 22 others when they stormed the aerospace headquarters.

Broadcasters showed footage of an exchange of gunfire in a car park, as well as the two armed attackers wearing backpacks as they entered the building.

Witnesses said they heard gunfire and an explosion. They said the blasts they heard may have been at different exits as employees left work for the day.

The witnesses said employees inside the building had been taken to shelters by the authorities and held there for some hours.

Workers were later evacuated from the TUSAS campus and buses were allowed to leave when the operation had ended.

Interior Minister Ali Yerlikaya said both attackers were killed after the terrorist incident.

“Sadly, we have five martyrs and 22 wounded in the attack. Three of the injured were already discharged from hospital, 19 of them under treatment,” he said.

Yerlikaya said the perpetrators were “highly likely” members of the outlawed PKK.

“The style of the act shows that it is highly likely the PKK that carried out the attack. Once identification is completed and other evidence become clearer, we will share more concrete information with you,” he said.

Turkish President Recep Tayyip Erdogan, alongside Russia’s Vladimir Putin at a BRICS conference in the Russian city of Kazan, condemned the attack and accepted Putin’s condolences.

NATO, the US and the European Union also condemned the attack.

TUSAS is Turkey’s largest aerospace manufacturer. It produces training craft, combat and civilian helicopters, as well as developing the country’s first indigenous fighter jet, KAAN.

Owned by the Turkish Armed Forces Foundation and the government, it employs more than 10,000 people.

NATO Secretary General Mark Rutte condemned the attack and said the military alliance would stand with its ally Turkey.
