The execution of ousted dictator Saddam Hussein is likely to be carried out within the next three days in Iraq, US television networks said.
NBC, CBS and Fox News Channel cited unnamed US military officials speaking on condition of anonymity, as their sources for the reports.
Sunday marks the last day of 2006 and the start of an Islamic festival to mark the end of the Haj, or month of pilgrimage.
Fox News reported a US military official as saying the Iraqi government was "anxious to get Saddam's execution done".
NBC said that the US military, which has kept Saddam in its custody during his trials for a 1982 massacre in the Shia town of Dujail and a second case of alleged genocide against Iraqi Kurds, had received a formal request from the Iraqi government to transfer him to Iraqi authorities.
CBS news said on Thursday that Saddam would be turned over to the Iraqi government within the next 36 hours.
In contrast, Fran Townsend, Homeland security advisor to US President George W Bush, told CNN on Thursday evening that Saddam would be transferred to Iraqi custody when requested by Baghdad officials, implying that the formal request and transfer had yet to happen.
Earlier this week, Iraq's highest court rejected Saddam's appeal against his death sentence, meted out for the killing of 148 Shias in Dujail, following an assassination attempt against Saddam.
