"Takfiri terrorists pose a trans-border threat to Iraq's neighboring countries," Zarif said during the telephone conversation on Thursday evening.
The Iranian foreign minister also reiterated the UN responsibility to seriously and effectively support the Iraqi nation and government in fighting terrorism.
Iraqi forces are continuing their battle against Takfiri terrorists as militants are advancing in Iraq, taking control of parts of the Arab country.
On June 10, Iraq’s northern Nineveh Province fell into the hands of militants from the so-called Islamic State of Iraq and the Levant (ISIL). The Takfiri attacks have reportedly forced more than half a million people in and around Mosul, the capital of Nineveh Province, to flee their homes.
While militants managed to take control of two areas in Diyala Province on Thursday, Iraqi forces also regained control of the Central city of Tikrit. Takfiri militants have vowed to march toward the capital, Baghdad.
Takfiri groups are reportedly entering Iraq from neighboring Syria and Saudi Arabia to undermine security in the country.
