An American forensic expert has testified at Saddam Hussein's genocide trial, showing pictures of bones and skulls of Iraqi Kurds shot during Operation Anfal in 1988.
Clyde Snow says his team exhumed the bodies of 27 people killed by firing squad from a mass grave in the village of Koreme. He also said soil samples from the village showed traces of mustard gas.
Snow said experts believe what they saw at Koreme was typical of what happened at scores of Kurdish villages during Operation Anfal, which the prosecution says killed 180,000 people.
Saddam objected to Snow's testimony because he is American. Saddam says experts from countries that did not take part in the invasion of Iraq should testify instead.
Meanwhile, U.N. human rights experts say Saddam's first trial was flawed and the ousted leader's death sentence should not be carried out.
The U.N. Human Rights Council's working group on arbitrary detention says Saddam's trial for the 1982 killings of Shi'ite villagers in Dujail fell short of international standards.
