Karwan Abdallah Tawfiq was the 20th witness to testify in the former Iraqi leader’s trial for genocide.
Tawfiq has described how his village was bombed and he and other villagers fled into the hills over the dead bodies of the victims.
"I saw with my own eyes all those broken limbs," he said.
It was the last thing he saw for some time as the chemical attacks burned his eyes and he became unconscious.
"After two months I regained consciousness. I was disoriented. After that I found myself with some friends at the Imam Khomeini hospital at Isfahan in Iran."
"I used to feel as if I was drunk the whole time. I spent six months in the hospital, and in all that time I was unable to see," he said.
Gas impact lasting
Tawfiq also described how he later gained asylum and medical treatment in the Netherlands.
The impact of the poison gas has been lasting as he showed the court by taking off his sunglasses to reveal heavily bloodshot eyes.
"Even my children are scared to see my eyes when I remove the glasses. My eyes are scary," he told the court. "Look at my eyes, look at my hands," he said to the court.
The chief judge Abdullah al-Ameri told him to put his glasses back on again.
Tawfiq added that he had been part of a successful lawsuit at the Hague against a Dutch arms trader who had sold chemical weapons to Saddam's regime.
He testified that European doctors were mystified by his wounds, saying they hadn't seen anything like this since the Second World War.
Saddam seized on the statement during cross examination.
"I would like to ask this man, did he see the results of the chemical weapons used by the Americans in Vietnam?"
The judge cut him off, saying that this was not a matter for the trial.
Tawfiq further explained how he escaped to the Netherlands on a fake name for "fear of the dictatorial regime which was chasing my friends."
"I applied under the name of Sardar Ali Abdallah. I changed my name and the date of birth" on the passport, he told the court.
Fake name
Hearing this, defence lawyer Badie Arif during his cross-examination said "all the details have been faked by him. How are we going to rely on his testimony?"
After the end of the session Arif told AFP he planned to sue the prosecutor for presenting a witness who had faked his name and fled the regime.
"He (the prosecutor) knew that this witness had gone on a fake name," said Arif.
The hearing also heard testimony from a female witness who described attacks on her village.
She said some of her relatives disappeared or were killed during the attacks.
Saddam and six of his former associates are on trial for genocide, war crimes and crimes against humanity.
They are accused of spearheading the 1987-1988 "Anfal" campaign in Iraq's northern Kurdish region.
Prosecutors say 182,000 Kurds were killed after their villages were bombed, burned and razed to the ground.
If found guilty, Saddam and his men face execution by hanging.
