President Obama: U.S. Military Authorized to Make Targeted Airstrikes in Northern Iraq

*Obama: Airstrikes to Be Taken Only if Necessary

*Obama: U.S. Can’t Turn Blind Eye to Potential Act of Genocide

MORE TO COME

The Obama administration was preparing plans late Thursday for airstrikes against Islamist militants in northern Iraq, and began an emergency airdrop of water and food to members of a religious minority trapped in the mountains by advancing Islamist militants, U.S. officials said.

The sudden acceleration of U.S. military activity reflected White House concern over a burgeoning crisis in the semiautonomous Kurdish region of Iraq as the militant group calling itself Islamic State closed in on the area and pressed an offensive against local forces, seizing areas long considered safe. Militants on Thursday took over the Mosul Dam, the country’s largest, according to a local resident.

The administration was actively considering U.S. airstrikes against the militant group’s positions to protect U.S. military and diplomatic personnel working in the northern Iraqi city of Erbil. Pentagon officials said no U.S. strikes had begun by Thursday evening. An Iraqi military official said the Iraqi air force conducted some airstrikes Thursday.

The White House and Pentagon have said they reserve the right to use force in Iraq to protect Americans, and repeated that stance Thursday. The U.S. troops in Erbil are part of a force of planners and advisers working in joint U.S.-Iraqi centers.

Washington has held off on any direct military involvement as the Obama administration pressures Iraqi lawmakers to form a new, more inclusive government. The U.S. rush to aid Kurdish areas of the country, long close to the U.S., sent an implicit U.S. suggestion that it might do more for the central government in Baghdad once it has a new government.

"We are sending a clear message to the Iraqi government," said a U.S. official.

The United Nations Security Council met in an emergency session on the Iraq crisis and expressed "deep outrage" about the hundreds of thousands of Iraqis—especially those from vulnerable minorities—who have been displaced and persecuted by Islamic State militants.

The U.S. has considered airstrikes before in Iraq, but backed down as the advance by Sunni militants slowed and the threat against Baghdad seemed to diminish. But the extremists have renewed their push in recent days, this time against Kurdish controlled territories.

At the same time, tens of thousands of Iraqi Christians fled an advance by Islamic State militants into the country’s Christian heartland in the north. It appears to be a strategic push by Islamic State toward the semiautonomous Kurdish region, so far insulated from the militant takeover of parts of Iraq and a haven for people displaced from other parts of the country.

The latest rapid advance by Islamic State on the Christian area and the crisis involving the Yazidis are both taking place in the same northern province, Nineveh, where the militant group took the provincial capital Mosul on June 10 and sent Iraq into its worst crisis in years.

An Iraqi military official said the Iraqi air force conducted strikes Thursday in Nineveh on the city of Mosul and closer to Erbil province, and on Tikrit in Salaheddine province. The air force has bombed insurgent positions in Mosul and in Tikrit—which Islamic State took on June 11, the day after it seized Mosul—and its surroundings as part of a counteroffensive, Iraqi officials say.

Insurgents took over six towns in northern Iraq over the past two days—two of them after the Kurdish regional forces guarding them, the Peshmerga, withdrew, local officials and residents said Thursday. The 190,000-strong Peshmerga have a fearsome reputation and are well-trained, but not well equipped. Many of the more battle-hardened fighters are now aging.

"People are fleeing because there is no trust that the Peshmerga can protect them," said Yonadam Kanna, a parliamentarian and the leader of the Assyrian Democratic Movement, one of the strongest Christian parties in Iraq.

"This isn’t an equal fight between the Peshmerga and the Islamic State," Mr. Kanna said. "The Islamic State has much bigger and more powerful weapons than the Peshmerga do. These people want to die and have lunch with the Prophet Muhammad. The Peshmerga want to live and go home to have dinner with their wives. They won’t play as dirty as the Islamic State does in war."

The Kurdish foreign minister welcomed Washington’s aid pledge but stressed that no commitments had been given to provide Kurdish fighters with weapons or ammunition to repel Islamic State advances.

In a telephone interview from Erbil, Falah Mustafa Bakir said Peshmerga retreats in recent days were calculated to protect civilians from indiscriminate attacks and didn’t represent a military collapse along the lines of the Iraqi army earlier this summer.

"President Obama considering the airdrop and other military options will be an important show of support," he said. "This is what is needed, especially for people stranded in Sinjar. These people are in dire need of whatever assistance is possible and an airdrop is the only way. We also welcome airstrikes," Mr. Bakir said.

On Sunday, the militants seized Sinjar, a Kurdish-controlled town with a large population of Yazidis, a Kurdish-speaking group that follows a pre-Islamic religion. U.N. groups have estimated as many as 40,000 Yazidis have fled to the mountains without food or water and are trapped there, with all access roads out controlled by Islamic State. The United Nations Children’s Fund said 40 refugee children have died.

The advancing militants killed some of the Yazidis who remained in the area known as the Sinjar plains, according to locals who fled and U.S. officials.

"They are unable to access food and water," said White House press secretary Josh Earnest. "They don’t have any access to shelter. They have fled persecution, and efforts to leave the mountain are blocked by ISIL [Islamic State] forces who are threatening to kill them. This is a terrible humanitarian situation."

The stranded Yazidis are the last surviving community in their ancestral homeland of the Yazidis, long misunderstood by the outside world as "devil-worshippers." The assault on the community is part of a pattern by extremists of stamping out non-Islamic religious observation.

Iraqi officials and aid workers say at least one airdrop over the Sinjar mountains coordinated by Baghdad and the Kurdistan Regional Government provided drinkable water. But officials said the attempt reached only a small number of the tens of thousands displaced.

U.S. intelligence reports on the fate of the Yazidis closely mirror dire media reports, officials said. Vian Dakhil, the only Yazidi in the Iraqi parliament, said this week 70 children had died and Islamic State had killed more than 500 men. She accused Islamic State of genocide against the Yazidi populations.

"There is a collective attempt to exterminate the Yazidi people," she said.

U.S. officials said they have received a formal request for assistance—but didn’t say if it was from the Kurdish regional authorities or the central government in Iraq. As part of the effort to send military advisers to Iraq, the U.S. has set up coordination centers in both Baghdad and Erbil, the Kurdish regional capital.

The advance of insurgents into Christian areas sent families packing into cars or fleeing on foot as the militants pushed their offensive closer to the semiautonomous Kurdish region.

Islamic State—a spinoff of al Qaeda that was previously known as the Islamic State of Iraq and al-Sham, or ISIS—pressed forward an offensive in northern Iraq after seizing Mosul.

The group, emboldened in Iraq after seizing parts of northern and eastern Syria, aims to carve out an Islamic state across borders of neighboring Middle Eastern nations.

In their latest rapid advance, Islamic State entered Tal Keif, some 10 miles north of Mosul in Nineveh province, late Wednesday, the town’s mayor said. They took over Qara Qosh, east of Mosul on Thursday morning, a security official said.

Two other towns in the area, Bartella and Karmalees, also fell under Islamic State control overnight, said Joseph Thomas, the Chaldean archbishop of Kirkuk and Sulaymaniya. He and local officials said the latest advance has nearly purged northwestern Iraq of its Christian population.

"Those towns are now devoid of their original inhabitants. The displaced people are roaming the roads and riding whatever vehicle they can to get out," the archbishop said.

Tal Keif Mayor Bassem Bello said people also fled his town by foot, as cars jammed the road to make the hourlong drive to the province of Dohuk—part of the Kurdish region—overnight.

"The Nineveh plain yesterday was emptied of its people," Mr. Bello said by telephone Thursday. "There is not a Christian town left standing." Mr. Bello said the majority of Tel Keif’s 30,000 residents fled; if anyone was left behind, he warned they were in great danger from the Sunni extremists on a campaign to seize territory and drive out Iraq’s religious and ethnic minorities.

The Mosul dam, a key source of electricity, would give Islamic State leverage over Baghdad—if the facility is damaged or destroyed, it could flood entire cities, even Baghdad, some 300 miles away. The dam provides electricity to and controls the water supply in Mosul and the surrounding area.

Iraqi Christians are thought to make up little more than 5% of the population of some 23 million people. Once one of the more vibrant Christian populations in the Middle East, 10 years of war and the rise of Islamic extremism already induced much of the country’s Christian minority to emigrate.

Those remaining have fled the latest Islamist threat in the hundreds of thousands, seeking safety in other northern villages or the eastern Kurdish regions.

Fighters from the group had taken two Kurdish towns even closer to Erbil, Makhmour and Gwair.

For residents of the city of Erbil, the flood of people into the Kurdish region and fears of the insurgents’ advance over the past few days has stirred widespread panic.

People stocked up on essentials at supermarkets and tried to book flights out of the area, but many were already overbooked, residents said. Security tightened as many more road checkpoints were put up. One resident said an appeal for Kurds to volunteer with the Peshmerga boomed out through a mosque speaker on Wednesday.
