Saddam's regime has long oppressed the 4 million Kurds living in northern Iraq, despite occasional alliances of convenience. In the late 1980s, more than 150,000 Kurds are believed to have been killed by the Iraqi leader's orders. In 1988, in the town of Halabja, a poison chemical attack wiped out an estimated 5,000 residents.
