BAGHDAD: Iraq's Prime Minister-designate Haider al-Abadi said Sunday during talks with Iran's foreign minister that international efforts would be necessary to destroy ISIS militants who have seized swaths of his country and of Syria.
Foreign Minister Mohammad Javad Zarif of Iran, a Shiite regional power likely to wield influence over the formation of Abadi's new cabinet, reaffirmed Tehran's support for Iraq's territorial unity and its fight against militants.
"Abadi pointed to the presence of many dangers posed in the region as a result of the existence of the terrorist gang Islamic State which requires regional and international efforts to exterminate this terrorist organisation," his office said in a statement after the talks with Zarif.
The advance of the Islamic State of Iraq and Greater Syria through northern Iraq has alarmed the Baghdad government and its Western allies, prompting the first U.S. airstrikes in Iraq since U.S. occupation forces pulled out in 2011.
The Sunni militant group sees Shiites - a majority in Iraq - as infidels who deserve to be killed and has driven thousands of non-Muslims from their homes.
Bombings across Iraq killed at least 35 people Saturday in apparent revenge attacks after Shiite militiamen machine-gunned a Sunni mosque in Diyala Province Friday, killing 68 worshippers in an attack that further deepens the country's sectarian conflict.
Critics have accused Iraq's outgoing prime minister, Nouri al-Maliki, a Shiite like Abadi, of fueling the conflict by pursuing a narrowly sectarian agenda that excluded Sunnis from positions of power and influence.
Abadi is now seeking support from Sunnis and ethnic Kurds to take on the ISIS insurgency - a policy of reaching out that Iran's Zarif praised Sunday.
"We feel very comfortable about the democratic process in Iraq which has reached to a logical result through selecting prime minister-designate Haider al-Abadi to form an inclusive government that comprises all Iraqi sects," Zarif told a news conference with Iraqi Foreign Minister Hoshiyar Zebari.
"The Islamic Republic of Iran will keep standing by your side. Iran backs the unity of Iraq and the stabilising of security and considers that as a priority in its foreign policy," he said.
Sunnis blame Iranian-trained Shiite militias for sectarian bloodshed, including kidnappings and killings. The militias say they are hunting down ISIS militants.
Bombings, kidnappings and execution-style shootings occur almost daily in Iraq, echoing the dark days of 2006-2007, the peak of a sectarian civil war.
Asked about reports that Iranian soldiers were fighting alongside Iraqi forces in the battle against ISIS, Zarif said:
"The information about the presence of Iranian soldiers in Iraq is not correct. We don't have a single Iranian soldier on Iraqi soil because Iraq does not need those soldiers."
ISIS militants have mostly routed Kurdish forces in the north in recent weeks, seizing more towns, oilfields and Iraq's largest dam. Backed by U.S. airpower, Kurdish forces later took back control of Mosul dam.
Although the U.S. air campaign launched this month has caused some setbacks for ISIS, they do not address the deeper problem of sectarian warfare which the group has fueled with its attacks on Shiites.
In retaliation for the airstrikes, ISIS released a video showing one of its black-clad fighters beheading U.S. journalist James Foley.
