How did the Turkish attack proceed?

The Turkish government has said at least five people were killed after an attack on aerospace company TAI, which produces drones and fighter jets for the military.

Turkey has said it was a terrorist attack and launched attacks on the armed separatist group PKK in response. Footage of the attack shows two heavily armed people arriving at TAI. It also shows a large explosion at the location.
