A deadly “terror” attack targeted a Turkish aerospace company in the capital Ankara, government officials said Wednesday.

Five people have been killed and 14 wounded in an attack on an aerospace firm near the Turkish capital of Ankara, the government said. Two attackers - a man and a woman - were killed in the skirmish after witnesses heard gunfire and an explosion at the site, interior minister Ali Yerlikaya said.

The strike came days after President Recep Tayyip Erdogan suggested parole for the PKK’s imprisoned leader and hours after a terrorist attack in Ankara. Turkey regularly conducts airstrikes against the PKK,

No group immediately claimed responsibility. Turkey’s interior minister said it was “most likely carried out” by the Kurdistan Workers’ Party, or PKK.

Recent gestures by Turkish leaders suggest the possibility of new peace talks with the group fighting for Kurdish autonomy.

Turkey continued its strikes in Syria and Iraq for a second day following the terrorist attack on a defense company in Ankara, in what Turkey said were targeted hits on PKK terrorist locations.

Footage broadcast on Turkish television and shared on social media Oct. 23 showed an attack on an aerospace company's headquarters near the capital, Ankara.
