"People would not have died, if politicians had reconciled. Kurds are on one side, the Shi'ites are on another side and the Sunnis are on one side. They do not have any mercy."
Baghdad has been hit by wave after wave of bombings.
The bloodshed comes as Prime Minister Nouri Maliki wages a war against Sunni militants in western Anbar province near the Syrian border.
Explosives and suicide bombs have been favored by Sunni extremists as they seek to target Shi'ite areas and intimidate their own religious community.
