Foreign Ministry Spokesman Seyed Abbas Mousavi deplored the terrorist attack at a mosque in Western Baghdad which killed and wounded tens of Iraqi citizens.
He also voiced sympathy with the Iraqi government and nation, specially the family members of the victims.
A suicide bomb blast at a Shiite mosque in Western Baghdad killed at least 10 people and wounded 30 others on Friday, Iraqi security officers said.
The explosion hit Imam Mahdi al Muntadhar Mosque in Baladiyat, near the massive and densely populated district of Sadr City.
"At least one attacker wearing a belt of explosives tried to enter the building but was stopped by the guards, and detonated himself outside," said one officer.
There are conflicting reports on the death toll, as some sources say seven people were killed in the attack.
Security forces were quickly deployed to cordon off the site.
There was no immediate claim of responsibility.
