The trial of Saddam Hussein had “serious flaws” that fell short of international judicial standards in reaching death sentences for the former Iraqi president and two senior members of his regime, a human rights group said Friday.

The report by Human Rights Watch – which examined an independent translation of the proceedings – came as a special tribunal in Baghdad neared the end of another trial of top Saddam era officials charged with crimes against humanity.

Saddam and two other top members of his regime were convicted of ordering the execution of more than 140 Shiite Muslims from the Iraqi city of Dujail following a 1982 attempt on Saddam’s life. Saddam was hanged Dec. 30.
