A series of bomb attacks rocked Iraq on Tuesday, leaving at least twelve people dead, Reuters reported.
The latest attacks come a day after 70 people, mostly Shi'ites, were killed across the country in a wave of bomb blasts.
Three roadside bombs exploded close to a livestock market in the northern city of Kirkuk, killing six and wounding many more. Two car bombs were also detonated in Tuz Khurmato, in the same province, killing three.
Meanwhile a suicide bomber killed three Iraqi soldiers at a checkpoint north of Baghdad.
Iraq has seen an escalation in sectarian violence over recent weeks, with 200 people being killed in such incidents in the last week, prompting fears of a Sunni-Shia conflict.
Iraq's Prime Minister, Nouri al Maliki, said on Monday that he will launch a comprehensive overhaul  of the country's security strategy, in the wake of widespread killings.
More than 700 people were killed in the country during April, the highest monthly figure for almost five years, according to UN figures.
