A suicide bombing at a rally in north-eastern Iraq has killed 30 people, the deadliest of a wave of attacks to hit Iraq
The attacker targeted a political gathering in the town of Khanaqin, which has a large Kurdish population.
Another 50 or more people were injured in the blast.
Iraqis are voting in the country's first parliamentary election since the withdrawal of American troops almost three years ago.
A total of at least 50 people have been killed in the latest attacks.
Al-Jazeera is reporting bloodshed has almost reached levels not seen since 2006-2007, when tens of thousands were killed in sectarian attacks.
Quoting United Nations figures, al-Jazeera says almost 1700 civilians were killed in just the first three months of this year.
