Security forces in Iraq are on high alert on the anniversary of the execution of the country's former president, Saddam Hussein.
His supporters are expected to gather at his power base in the city of Tikrit, and at his grave nearby.
Police and troops are patrolling the village of Awja, Mr Hussein's birthplace and where he now lies buried.
Fresh slogans have been painted on walls in Tikrit in support of the former president and Sunni leader who was hanged for crimes against humanity.
Iraqi security officials say they are ready to deal with any civil unrest in the heartland areas of Sunni Iraq north and west of Baghdad, from where most of the senior officials in his regime came.
In northern Baghdad's strongly Sunni district of Adhamiyah, posters of Saddam are pasted on to walls to mark one year since his execution for the killing of around 140 Shias from the village of Dujail after an attempt on his life there in 1982.
Saddam was hanged at the age of 69 in Baghdad just minutes before the Muslim festival of Eid al-Adha began on 30 December last year.
Sunnis celebrated Eid al-Adha this year on 19 December, when dozens of Saddam's supporters gathered in Awja to lay flowers on his grave and pay their respects.
Footage captured on a mobile phone showed the final minutes of his life at the gallows, which triggered outrage around the world and embarrassed Iraq's Shia-led government.
Even US President George W Bush, who hailed Saddam's capture in December 2003 after the March US-led invasion toppled his regime, sharply criticised the manner of his execution.
In a television interview in January he said the hanging resembled a sectarian 'revenge killing' and had made it harder to end the violence plaguing Iraq.
Iraqi officials ordered that Saddam be buried in the dead of night without the lying in state traditionally accorded to presidents.
The hanging further deepened the rift between Sunnis and Shias that was inflamed by the bombing of a revered Shia shrine by suspected al-Qaeda militants in February last year.
Saddam lies buried near the graves of his sons Uday and Qusay, who were key figures in his regime and were killed in a gun battle with US forces in the main northern city of Mosul in July 2003.
The village of Dawr, just south of Tikrit, where Saddam was captured hiding in a hole by US forces, was put under indefinite curfew yesterday.
