Iraqi Shiite and Kurdish MPs have condemned the delay in carrying out the executions of "Chemical Ali" and two other convicted former officials of the Saddam Hussein regime.
Ali Hassan al-Majid, Sultan Hashim al-Tai, Saddam's defence minister, and Hussein Rashid al-Tikriti, his armed forces deputy chief of operations, were sentenced to death on June 24.
Kurdish and Shiite deputies called for the executions to be carried out without further delay.
The US military will not hand the condemned men over until the legal row between Iraqi officials over the execution is resolved.
Two members of the presidential council President Jalal Talabani, and Vice President Tareq al-Hashemi, have refused to sign the execution orders.
