Scenes of destruction in Baghdad after a series of coordinated car bombs and roadside blasts 10 years to the day since the US-led invasion that toppled Saddam Hussein. Officials say more than 30 people were killed and 80 wounded as small restaurants, bus stops and groups of labourers were targeted. The attacks all happened within a one-hour period.

Updates from Al-Jazeera report that the death toll from Tuesday's blasts is now 56 with 88 people wounded, the extent of their injuries unknown at this time. Ten car bombs, including two detonated by suicide bombers, one roadside bomb and two gun attacks struck in and around the Iraqi capital during morning rush hour.

The attacks cames as the cabinet announced on Tuesday that it would postpone provincial elections in two provinces that were scheduled for April by up to six months over security concerns.

Polls in Anbar province in west Iraq and Nineveh in the north have been delayed, Ali Mussawi, the Iraqi premier's spokesman said.

Mussawi said that candidates have been threatened and killed, while there were also requests for a delay from the two provinces.

Several provincial elections candidates have also been killed in attacks in recent weeks.

It appeared that elections in the 12 other provinces where they were set to be held on April 20 would go ahead as scheduled.

Violence in Iraq has decreased from its peak in 2006 and 2007, attacks still remain common, killing 220 people in February alone.
