BAGHDAD — Iraq’s president named a new prime minister to end Nuri al-Maliki’s eight-year rule Monday, but the veteran leader refused to go after deploying militias and special forces on the streets, creating a dangerous political showdown in Baghdad.
Washington, which helped install Maliki after its 2003 invasion that toppled Saddam Hussein, congratulated Haidar al-Abadi, a former Maliki lieutenant who was named by President Fouad Masoum to replace him.
Maliki said in a televised speech the president’s decision to name a replacement for him was a “dangerous violation” of the constitution and, flanked by political allies, he vowed, “We will fix the mistake.”
Maliki’s son-in-law, Hussein al-Maliki, called the move “illegal” and said it would be overturned in court. “We will not stay silent,” he said.
Washington delivered a stern warning to Maliki not to “stir the waters” by using force to cling to power.
A Shiite Muslim Islamist, Maliki is blamed by his erstwhile allies in Washington and Tehran for driving the alienated Sunni minority into a revolt that threatens to destroy the country. Leaders of Iraq’s Sunni and Kurdish communities have demanded he go, and many fellow Shiites have turned against him.
U.S. President Barack Obama said the naming of a new prime minister was an important stride for Iraq toward rebuffing Islamic State militants, who have overrun large swaths of northern Iraq.
Obama said he spoke with Abadi to congratulate him and to urge him to quickly form a new cabinet that is broadly representative of Iraq’s different ethnic and religious communities.
U.N. Secretary-General Ban Ki-moon also praised the naming of Abadi and urged him to seek a broad-based government acceptable to all components of Iraqi society, the United Nations said.
The new political crisis comes just days after Washington launched its first military action in Iraq since pulling its troops out in 2011. U.S. warplanes have bombed Sunni insurgents from the Islamic State, who have marched through northern and western Iraq since June.
Washington says it is taking limited action to protect a Kurdish autonomous region and prevent what Obama called a potential “genocide” of religious minorities targeted by the militants.
The Pentagon said U.S. airstrikes conducted since Friday have slowed the operational tempo of the Islamic State but are unlikely to substantially weaken the group.
U.S. aircraft hit four Islamic State checkpoints Monday and destroyed several of the group’s vehicles near Mount Sinjar, where thousands of people of the Yazidi religious sect have taken refuge, the Pentagon said.
Washington is also directly supplying weapons to Kurdish fighters, U.S. officials said. The weapons were supplied by the Central Intelligence Agency but the Pentagon may soon start arming the Kurds, the officials said. They declined to specify when the supply program began or what sort of arms it included.
Islamic State fighters made new gains against Kurdish forces despite four days of U.S. airstrikes, while Baghdad, long braced for the Sunni fighters to attack, was now tensing for possible clashes between Maliki and rivals within the Shiite majority.
President Masoum asked Abadi to form a government that could win the support of all groups in a parliament elected in April. In remarks broadcast on television, Masoum, a Kurd, urged Abadi to “form a broader-based government” over the next month.
Abadi urged national unity against the “barbaric” Islamic State, which has driven tens of thousands from their homes as it swept aside Baghdad’s troops to consolidate a “caliphate” in Iraq and Syria.
“We all have to cooperate to stand against this terrorist campaign launched on Iraq and to stop all terrorist groups,” he said in broadcast remarks after meeting Masoum.
As police and elite armed units, many equipped and trained by the United States, locked down the capital’s streets, U.S. Secretary of State John Kerry aimed a stark warning at Maliki against fighting to hold on to power.
“There should be no use of force, no introduction of troops or militias in this moment of democracy for Iraq,” Kerry said. “The government formation process is critical in terms of sustaining stability and calm in Iraq, and our hope is that Mr. Maliki will not stir those waters.
“There will be little international support of any kind whatsoever for anything that deviates from the legitimate constitution process that is in place and being worked on now.”
Under Iraq’s post-Saddam governing system, designed to avert conflict by giving all groups a stake, the speaker of parliament is a Sunni and the largely ceremonial president a Kurd. Most authority is wielded by the prime minister, a Shiite.
Maliki’s opponents accuse him of abusing the system by keeping key security posts in his own hands instead of sharing them with other groups, alienating Sunnis in particular by ordering the arrest of their political leaders. Islamic State fighters were able to exploit that resentment to win support from other Sunni armed groups.
Maliki’s Shiite State of Law bloc emerged as the biggest group in parliament in the April election, but does not have enough seats to rule without support from Sunnis, Kurds and other Shiite blocs, nearly all of which demand he go.
He has nevertheless stayed on in a caretaker capacity while arguing that the constitution requires his bloc to be given the first opportunity to form a government. He has used courts before to keep power: in the previous election in 2010, when State of Law was second, a court let him form a cabinet.
A U.S. official insisted Washington had not been involved in the selection of Abadi but said “everybody is pretty relieved that they have chosen somebody and that it was not Maliki.”
Maliki also appears to have alienated his supporters in Iran, the regional Shiite power, which has sent military advisers to help organize the battle against the Islamic State. Iraq’s most influential Shiite cleric, Ali Sistani, all but ordered Maliki to leave power Friday, declaring that politicians who cling to power were making a “grave mistake.”
Obama says a more inclusive government in Baghdad is a precondition for more aggressive U.S. military support against the Islamic State. He has rejected calls in some quarters for a return of U.S. ground troops, apart from several hundred military advisers sent in June.
The Islamic State, which sees Shiites as heretics who deserve to be killed, has ruthlessly moved through one town after another, using tanks and heavy weapons it seized from soldiers who have fled by the thousands.
On Monday, police said the fighters had seized the town of Jalawla, 70 miles northeast of Baghdad, after driving out the forces of the autonomous Kurdish regional government.
On Sunday, a government minister said Islamic State militants had killed hundreds of people from the small, Kurdish-speaking Yazidi religious sect, burying some alive and taking women as slaves. No confirmation was available of the killings.
Thousands of Yazidis have taken refuge in the past week on the arid heights of Mount Sinjar, close to the Syrian border. The Islamic State considers the Yazidis, who follow an ancient faith derived from Zoroastrianism, to be “devil worshippers.”
A U.N. official said Monday that thousands of Yazidis have been able to escape in the past three days with help from Kurdish security forces and others. But the official said many are still trapped on the mountain.
The bloodshed could increase pressure on Western powers to do more to help those who have fled the Islamic State’s offensive. They have already dropped supplies and U.S. aircraft have been bombing the militants since Friday.
