From 1992 to the United States-led coalition invasion of Iraq in 2003, there were two NFZs in Iraq. The NFZ in the north of Iraq was established shortly after the Gulf War, extending from the 36th parallel northwards. In August 1992 the NFZ in the south to the 32nd parallel was established, but in 1996 it was expanded to the 33rd parallel. The northern NFZ was initially part of Operation Provide Comfort relief operations to a persecuted Kurdish minority in Iraq, and was followed on by Operation Northern Watch. The southern NFZ was maintained by Operation Southern Watch.
