Iraqi Kurd residents visit the cemetery for victims of the 1988 chemical attack in the Kurdish town of Halabja, near Sulaimaniya, 260 km (160 miles) northeast of Baghdad, March 16, 2013. Iraqi Kurds on Saturday marked the 25th anniversary of the chemical attack on the northern Iraqi city of Halabja by Saddam Hussein’s forces. Up to 5,000 people may have been killed by chemical gas, villages were razed and thousands of Kurds were forced into camps during the 1988 Anfal genocidal campaign against Iraqi Kurds.
