The Kurdistan Workers' Party or PKK is a Kurdish militant political organization and armed guerrilla movement, which historically operated throughout Kurdistan, but is now primarily based in the mountainous Kurdish-majority regions of southeastern Turkey and northern Iraq. Since 1984, the PKK has utilized asymmetric warfare in the Kurdish–Turkish conflict. Although the PKK once sought an independent Kurdish state, in the 1990s its aims shifted toward autonomy and increased rights for Kurds within Turkey.
