In a declassified 1991 report, the CIA estimated that Iran had suffered more than 50,000 casualties from Iraq's use of several chemical weapons, though current estimates are more than 100,000 as the long-term effects continue to cause casualties. The official CIA estimate did not include the civilian population contaminated in bordering towns or the children and relatives of veterans, many of whom have developed blood, lung and skin complications, according to the Organization for Veterans of Iran. According to a 2002 article in the "Star-Ledger", 20,000 Iranian soldiers were killed on the spot by nerve gas. As of 2002, 5,000 of the 80,000 survivors continue to seek regular medical treatment, while 1,000 are hospital inpatients.
