BAGHDAD/WASHINGTON - Iraq has asked the United States for air support in countering Sunni rebels, the top US general said on Wednesday, after the militants seized major cities in a lightning advance that has routed the Shi'ite-led government's army.
But General Martin Dempsey, the chairman of the US military's Joint Chiefs of Staff, gave no direct reply when asked at a congressional hearing whether Washington would agree to the request.
Baghdad said it wanted US airstrikes as the insurgents, led by fighters from the Islamic State of Iraq and the Levant, or ISIL, battled their way into the biggest oil refinery in Iraq and the president of neighbouring Iran raised the prospect of intervening in a sectarian war that threatens to sweep across Middle East frontiers. "We have a request from the Iraqi government for air power,"Dempsey told a Senate hearing in Washington. Asked whether the United States should honour that request, he said: "It is in our national security interest to counter ISIL wherever we find them." US officials, speaking on condition of anonymity, said the Iraqi request had included drone strikes and increased surveillance by US drones, which have been flying over Iraq for some time.
In the Saudi city of Jeddah, Iraqi Foreign Minister Hoshyar Zebari said Baghdad had asked for airstrikes "to break the morale" of ISIL.
While Iraq's ally, Shi'ite Muslim power Iran, had so far not intervened to help the Baghdad government, "everything is possible", he told reporters after a meeting of Arab foreign ministers.
US President Barack Obama briefed congressional leaders on Wednesday on efforts to get Iraqi leaders to "set aside sectarian agendas," reviewed options for "increased security assistance" and sought their views, the White House said.
A senior administration official said afterward that Obama did not lay out a course of action at the meeting and had yet to make a final decision.
But a US national security source said the administration had quietly started consulting Congress about a plan for redirecting some current intelligence funding to help finance expanded US operations in Iraq.
Obama is facing pressure from US lawmakers to persuade Iraqi Prime Minister Nuri al-Maliki to step down over what they see as failed leadership in the face of the insurgency threatening his country.
Sunni fighters were in control of three-quarters of the territory of the Baiji refinery north of Baghdad, an official said there, after a morning of heavy fighting at gates defended by elite troops who have been under siege for a week.
ISIL aims to build a Sunni caliphate ruled on mediaeval precepts, but the rebels also include a broad spectrum of more moderate Sunnis furious at what they see as oppression by Baghdad.
Some international oil companies have pulled out foreign workers. The head of Iraq's southern oil company, Dhiya Jaffar, said Exxon Mobil had conducted a major evacuation and BP had pulled out 20 per cent of its staff. He criticised the moves, as the areas where oil is produced for export are mainly in the Shi'ite south and far from the fighting.
Washington and other Western capitals are trying to save Iraq as a united country by leaning hard on Maliki to reach out to Sunnis, the minority who ran Iraq until US troops deposed dictator Saddam Hussein after the 2003 invasion.
Maliki met Sunni and Kurdish political opponents overnight, concluding with a frosty, carefully staged joint appearance at which an appeal for national unity was read out.
In a televised address on Wednesday, Maliki appealed to tribes to renounce "those who are killers and criminals who represent foreign agendas".
But Maliki's government has so far relied almost entirely on his fellow Shi'ites for support, with officials denouncing Sunni political leaders as traitors. Shi'ite militia - many believed to be funded and backed by Iran - have mobilised to halt the Sunni advance, as Baghdad's million-strong army, built by the United States at a cost of $25 billion, crumbles.
Maliki announced on Wednesday that 59 officers would be brought to court for fleeing their posts last week as the insurgents seized Mosul, northern Iraq's biggest city.
Like the civil war in Syria next door, the new fighting threatens to draw in regional neighbours, mustering along sectarian lines in what fighters on both sides depict as an existential struggle for survival based on a religious rift dating to the 7th century.
Iranian President Hassan Rouhani made the clearest declaration yet that the Middle East's main Shi'ite power, which fought a war against Iraq that killed a million people in the 1980s, was prepared to intervene to protect Iraq's great shrines of Shi'ite imams, visited by millions of pilgrims each year. "Regarding the holy Shi'a shrines in Karbala, Najaf, Kadhimiya and Samarra, we announce to the killers and terrorists that the great Iranian nation will not hesitate to protect holy shrines," Rouhani said in an address to a crowd on live TV.
He said many people had signed up to go to Iraq to fight, although he also said Iraqis of all sects were prepared to defend themselves: "Thanks be to God, I will tell the dear people of Iran that veterans and various forces - Sunnis, Shias and Kurds all over Iraq - are ready for sacrifice." Iraqi troops are holding off Sunni fighters outside Samarra north of Baghdad, site of one of the main Shi'ite shrines. The fighters have vowed to carry their offensive south to Najaf and Kerbala, seats of Shi'ite Islam since the Middle Ages.
Saudi Arabia, the region's main Sunni power, said Iraq was hurtling towards civil war. Foreign Minister Prince Saud al-Faisal, in words clearly aimed at Iran and at Baghdad's Shi'ite rulers, deplored the prospect of "foreign intervention"and said governments needed to meet "legitimate demands of the people".
Maliki's government has accused Saudi Arabia of promoting"genocide" by backing Sunni militants. Riyadh supports Sunni fighters in Syria but denies aiding ISIL.
The Baiji refinery is the fighters' immediate goal, the biggest source of fuel for domestic consumption in Iraq, which would give them a grip on energy supply in the north where the population has complained of fuel shortages.
The refinery was shut on Tuesday and foreign workers flown out by helicopter. "The militants have managed to break into the refinery. Now they are in control of the production units, administration building and four watch towers. This is 75 per cent of the refinery," an official speaking from inside the facility said.
The government denied the refinery had fallen. Counterterrorism spokesman Sabah Nouri insisted forces were still in control and had killed 50 to 60 fighters and burned six or seven insurgent vehicles after being attacked from three directions.
Oil prices rose on news the refinery was partly in rebel hands.
Last week's sudden advance by ISIL - a group that declares all Shi'ites to be heretics deserving death and has proudly distributed footage of its fighters gunning down prisoners lying prone in mass graves - is a test for Obama, who pulled US troops out of Iraq in 2011.
Obama has ruled out sending back ground troops and US officials have even spoken of cooperating with Tehran against the mutual enemy. But the White House said more talks with Iran about dealing with the crisis in Iraq, which have taken place on the sidelines of meetings on Tehran's nuclear programme, are unlikely for the time being.
US Senate Majority Leader Harry Reid said he did not back sending US troops into the conflict in Iraq, which he described as a "civil war". "The Maliki government, candidly, has got to go if you want any reconciliation," said Senator Dianne Feinstein, Democratic chairwoman of the Senate Intelligence Committee.
US Vice President Joe Biden spoke on Wednesday with three Iraqi leaders, including Maliki, to urge unity against insurgents and to emphasise the need to form an inclusive government after April's elections.
In his call with Maliki, the White House said Biden"underscored that the United States stands ready to enhance our support to all Iraqis in their fight against ISIL. At the same time, he emphasised the need for the Prime Minister - and all Iraqi leaders - to govern in an inclusive manner, promote stability and unity among Iraq's population, and address the legitimate needs of Iraq's diverse communities." Western countries fear an ISIL-controlled mini-state in Syria and Iraq could become a haven for militants who could then stage attacks around the globe.
In a rerun of previous failed efforts at bridging sectarian and ethnic divisions, Shi'ite, Sunni and Kurdish leaders met late on Tuesday behind closed doors. They later stood before cameras as Ibrahim al-Jaafari, a Shi'ite politician who held the post of prime minister before Maliki, read a statement. "No terrorist powers represent any sect or religion,"Jaafari said in the address, which included a broad promise of"reviewing the previous course" of Iraqi politics. Afterwards, most of the leaders, including Maliki and Usama al-Nujaifi, the leading Sunni present, walked away from each other in silence.
