Iraq's fugitive vice-president Tariq al-Hashemi has been sentenced to death in absentia after a court found him guilty of running death squads.
The court ruling came as at least 45 people were killed in a wave of about 24 attacks across Iraq.
Hashemi was the most senior Sunni Muslim in the predominantly Shia Iraqi government until he was charged last December and went on the run.
The charges against him sparked a political crisis in Iraq.
Other Sunni politicians denounced Shia Prime Minister Nouri al-Maliki - who issued the warrant for Mr Hashemi - as a dictator, accusing him of deliberate provocation that risked plunging the country back into sectarian conflict.
Correspondents say the fragile government coalition between Sunnis, secularists and Shia has seemed in danger of collapse ever since.
Sunni insurgents linked to al-Qaeda have been blamed for much of the recent violence in Iraq.
Sunday saw a fresh wave of killings:
In the deadliest single incident, 11 soldiers died in a shooting and bombing attack on an army base north of Baghdad
In the south-eastern city of Amara, two car bombs exploded outside a Shia shrine, killing at least 14 people and wounding more than 60, local officials said.
Seven police officers were killed by a bomb in the northern city of Kirkuk, officials said
Ten soldiers were killed in a dawn raid on a military base in Dujail, north of Baghdad, according to officials
In Nasiriya, in the south, a bomb exploded outside the French honorary consulate, killing one person, according to the city's website. The French government condemned the blast
There were also attacks in Tuz Khurmatu, Baquba, Basra and Samarra.
The Iraqi government issued the warrant for Hashemi's arrest on 19 December 2011, the day after the last US troops left the country.
On 20 December 2011, arrest warrant issued for him on charges of running death squads; he flees to northern Iraq
In April 2012, he leaves Iraq, going to Qatar and Saudi Arabia before arriving in Turkey
In September 2012, convicted and sentenced to death in absentia; 30 days to appeal
He fled first to the largely autonomous Kurdish north of the country, and from there to Qatar and on to Turkey.
Prosecutors said Hashemi was involved in 150 killings. During his trial in absentia in Baghdad, some of his former bodyguards said Mr Hashemi had ordered murders.
He says the charges against him are politically motivated and has accused PM Maliki of fuelling sectarianism.
On Sunday, an Iraqi court found Hashemi and his son-in-law guilty of two murders and sentenced him to death by hanging. The judge dismissed a third charge for lack of evidence.
Although violence has decreased since its peak in 2006 and 2007, attacks have escalated again after the withdrawal of US troops from Iraq at the end of last year, amid increasing political and sectarian tensions.
The Iraqi government has been hampered by divisions between Sunni, Shia and Kurdish political groups.
The Iraqi government said July 2012 was the deadliest month in nearly two years, with 325 people killed.
Former Iraqi leader Saddam Hussein was a Sunni, and many Sunnis believe they are being penalised by Shias, who have grown in influence since the US invasion.
Sunnis have accused Mr Maliki of taking an authoritarian approach to government.
