'Chemical Ali' executed in Iraq after Halabja ruling
Ali Hassan al-Majid, a former Iraqi official known as "Chemical Ali", has been executed by hanging, a government spokesman has announced.
Majid, an enforcer in Saddam Hussein's regime and his cousin, had earlier been sentenced to death four times for genocide and crimes against humanity.
Earlier this month, he was sentenced to death for ordering the gas attack on the Kurdish town of Halabja in 1988.
It is believed that about 5,000 people died in the attack.
Iraqi jets swooped over Halabja and for five hours sprayed it with a lethal cocktail of mustard gas and the nerve agents Tabun, Sarin and VX.
Majid was "executed by hanging until death", Iraqi government spokesman Ali al-Dabbagh said in a statement
"The execution happened without any violations, shouting or cries of joy," he added, in sharp contrast to Saddam's death on the gallows in 2006.
Iraqi state television, al-Iraqiya, broadcast pictures of what it said was the execution of Majid, although the BBC has not yet confirmed the authenticity of the images.
News of the hanging came shortly after three suicide car bombs struck in central Baghdad. It was not immediately clear whether the attacks were linked to his execution.
Majid was first sentenced to hang in June 2007 for his role in a military campaign against ethnic Kurds, codenamed Anfal, that lasted from February to August of 1988.
In December 2008 he also received a death sentence for his role in crushing a Shia revolt after the 1991 Gulf War.
In March 2009 he was sentenced to death, along with others, for the 1999 killings of Shia Muslims in the Sadr City district of Baghdad.
The BBC's Jim Muir in Baghdad says Majid could have been hanged earlier - after his first death sentence for the Anfal campaign.
But it was important to Iraqi Kurds to see him convicted of the Halabja attack, seen as one of the worst atrocities of Saddam Hussein's regime.
Our correspondent says there will be great rejoicing or, at the very least, quiet relief among both Iraq's Shia and Kurdish communities, which have suffered greatly at his hands.
There was a mixed reaction from ordinary Iraqis to news of the execution.
"I give my condolences to the Iraqi people on the death of Ali Hassan al-Majid, who was killed by traitors and hooligans," said a resident of Majid's home town, Tikrit.
But Baghdad resident Ali Suhail said the execution was just: ''He had executed so many people. So he deserves to be executed."
A resident of Halabja also said he was pleased: ''We, the families of those killed in the attack on Halabja, are very pleased to hear that Ali Hassan al-Majid was executed.
"Once again we call upon the Iraqi people and government to be united and serve the Iraqi people and families of those killed in poison gas attack."
Majid - the King of Spades in the US military's pack of cards of most-wanted Iraqis - was arrested in August 2003.
He has refused to express remorse at any of his trials, insisting that he was acting in the interests of Iraqi security.
The Iraqi High Tribunal was set up to try former members of Saddam Hussein's mainly Sunni government and was the same one that sentenced the former president to death.
Footage of Saddam's execution in December 2006 was posted on the internet.
It showed the dictator being confronted by opponents who jeered and clapped as he was being hanged.
