RNA - "The attack against the innocent civilians in Kirkuk province is suspicious," Qassemi said.
The Iranian foreign ministry spokesman extended condolences and sympathized with the bereaved families of the victims as well as the Iraqi people and government.
Qassemi urged pursuing the case to clarify different dimensions of the incident.
"Raiding the civilians is not acceptable and has no justification," he added.
A number of Iraqi civilians lost their lives and a number of them were injured following a raid by the US-led coalition on a mourning ceremony in Kirkuk.
On Friday, Iranian Foreign Ministry Bahram Qassemi strongly condemned the recent suicide attack by ISIL's terrorists on a power generation center near the city of Kirkuk which killed four Iranian technicians.
"These are the last breath of terrorists in Iraq and they are to take the revenge of their humiliating defeats in the battlefields by carrying out blind terrorist operations and killing defenseless civilians," Qassemi said.
Qassemi sympathized with the families of the Iranian victims of the terrorist attack.
On Thursday, three bombers stormed a power plant under construction by an Iranian company near Dibris town, located about 40 kilometers Northwest of Kirkuk city.
A dozen Iraqi administrators and engineers and four Iranian technicians were among those killed in the raid, which took place at around 6:00 local time, the town’s mayor Abdullah Nureddin al-Salehi said.
He said Iraqi security forces engaged the attackers, killing one of them. The other two armed men blew themselves up as soon as they were surrounded, the mayor added.
