There were many allegations that the government of Ba'athist Iraq under Saddam Hussein provided support for the Kurdistan Workers' Party (PKK), including sanctuary, weapons, and logistical support, mainly in the period from 1980 until 2003. The PKK was one of several designated terrorist groups that Saddam Hussein allegedly supported.
