Participants observed five minutes of silence in memory of 5,000 Kurds killed during a poison gas attack by forces of former Iraqi dictator Saddam Hussein. The 1988 attack is one of the most infamous massacres of Saddam's anti-Kurd "Anfal" campaign. Iraqi Kurds have sought reparations from the post-Saddam government in Baghdad, as well as help for the thousands of people who have suffered after-effects of the attack. In a statement released Tuesday, the Kurdistan Regional Government of Iraq said the anniversary is also a time to "heal, seek closure and look forward." In January, the Iraqi government executed Saddam Hussein's cousin, Hassan al-Majid, for the poison gas attack and other crimes against humanity. He was widely known as "Chemical Ali." .
