Factbox-Ankara gun assault revives memories of past attacks in Turkey

Two attackers killed five people and wounded 22 others on Wednesday in a gun attack on the headquarters of Turkey's largest aerospace manufacturer TUSAS that Ankara blamed on the Kurdistan Workers Party (PKK) militant group.

There has been no claim of responsibility but Interior Minister Ali Yerlikaya said at least one of the two attackers was confirmed to be a PKK member. Turkey responded by launching air strikes on PKK targets in Syria and Iraq.
