Iraq's prime minister blames Arab states for fanning the flames of violence in his country by turning a blind eye to the rulings of hard-line religious leaders, Press TV reported.
As US troops are preparing to leave the Iraqi cities, there has been a wave of deadly terrorist attacks, which has killed hundreds of Iraqis.
Nouri al-Maliki did not mention any country or group by name, but said, "There are states, which are silent on fatwas (Islamic decrees) urging killings and branding others as infidels," Iraq's Azzaman newspaper reported on Saturday.
Analysts believe that Maliki was mainly pointing to Saudi radical clerics who see killing of Muslim Shias as a religious duty.
Several bombings over the past three days in and around Baghdad killed nearly 100 people.
Shias make up about 60 percent of Iraq's population.
