A car bomb and a suicide bomber killed 60 people and injured 110 more in a double attack in Baghdad today.
Many of the victims were students blown up as they waited for cars to take them home at the entrance to the al-Mustansiriya University.
The head of the university, Takki Moussawi, has cancelled classes for two days.
At least 25 people were killed by four other bombs around the city, including another twin attack in one location.
A roadside bomb followed by a blast from a motorcycle rigged with explosives killed 15 people and injured 70 near a Sunni mosque in Khilani in central Baghdad.
Earlier in another central Baghdad area, Karrada, police had just succeeded in defusing a roadside bomb when another bomb exploded, killing four people, including two police. Another car bomb in Sadr City, a Shi'ite militia stronghold, killed six.
And ten more people were killed in a drive-by shooting in Binoog, a mixed neighbourhood not far from Mustansiriya.
34,000 civilian deaths in 2006 - UN
The UN said this morning that more than 34,000 Iraqi civilians were killed in violence last year.
The figure was announced at a news conference in Baghdad by the UN's human rights chief in the country, Gianni Magazzeni.
Mr Magazzeni said that, according to his figures, more than 36,000 people were wounded in 2006.
He accused the Iraqi government of failing to provide security and blamed some of the violence on militias colluding with or working inside the police and army.
The figures are much higher than any statistics issued by the Iraqi government, which said the UN had 'grossly exaggerated' the number of deaths.
The report, which is based on data from hospitals compiled by the Iraqi Health Ministry and from Baghdad morgues, said 6,376 civilians were killed in November and December alone.
That was a rate of 105 killed across Iraq every day, compared to 120 a day in September and October when 7,054 civilians were killed.
Mr Magazzeni said most of those killed in November and December died of gunshot wounds, a factor that he said indicated that they were victims of so-called 'death squad killings' rather than bombings.
