(CNN) — The militant group that has been ruthlessly fighting to take control of Iraq has apparently posted chilling photos on jihadi Internet forums seeming to show the executions of Iraqi security forces.
CNN cannot independently confirm the authenticity of the images purportedly posted by ISIS, or the Islamic State in Iraq and Syria. CNN is examining the terrain in the images, some of the signage on buildings in several of the pictures and the uniforms of the apparent victims. Those details suggest the photos are real and were taken in Iraq.
A caption on some of the images: “apostates heading to their hole of doom.”
ISIS, an al Qaeda splinter group, wants to establish a caliphate, or Islamic state, in the region that would stretch from Iraq into northern Syria. The group has had substantial success in Syria battling Syrian President Bashar al-Assad’s security forces.
ISIS’s quick advance in Iraq has been helped by many Sunnis who feel that the Shiite-dominated government has marginalized them.
On Friday, a tweet on what was claimed to be an ISIS Twitter account claimed that its members killed at least 1,700 Shiites. CNN was unable to verify the authenticity of the account, and the account appeared to have been taken down Sunday.
The militant group continued its assault Sunday. Iraqi security forces and gunmen believed to be ISIS clashed near al-Khalis, which is about 18 miles from Baquba, police officials in that Iraqi city told CNN.
Baquba is about 37 miles northeast of Baghdad, the capital. ISIS seized Iraq’s second-largest city, Mosul, last week and have threatened to march on Baghdad.
“Mosul didn’t fall,” a defiant Iraqi Prime Minister Nuri al-Maliki told military leaders in Baghdad in a speech televised Sunday on state TV. “The ones who have fallen are the politicians who have bet against Iraq.” The Prime Minister said, “We will not allow anyone to divide the Iraqi people.”
Al-Maliki called on his top brass and soldiers to march and fight against ISIS, while criticizing Iraqi politicians conspiring against their homeland, and Iraqi soldiers who have refused to continue to fight when confronted by ISIS.
“We will march on every inch, with all our weapons, with all our will and faith, so we can liberate and cleanse every inch of Iraq — from the southernmost point to the furthest point in the north,” he exhorted the military leaders.
Also Sunday, ISIS gained control of two villages in Adhaim, a move that constituted the militants’ first push into Diyala province, which is northeast of Baghdad.
Baquba, Diyala’s capital, is an ethnically-mixed city, though Sunnis represent a slight majority.
Given Baquba’s proximity to Baghdad, if Baquba were to fall, it could give ISIS militants three-pronged access to Baghdad — from Anbar province to the west, Ninevah and Salahuddin provinces to the north and from Diyala province from the northeast.
In other violence Sunday, three mortar rounds landed in al-Khalis, near a recruitment center opened recently for volunteers to join the Iraqi army in their fight against ISIS. Officials could not provide more details.
And, the northwest Iraqi city of Tal Afar fell to ISIS militants, according to Iraqi Gen. Mohammed al-Quraishi. Many of Tal Afar residents — ethnic minority Shiite Turkmen — fled the fighting by heading north toward Iraq’s Kurdish region. Tal Afar is in northwest Iraq in Nineveh province, midway between the country’s border with Syria and the Iraqi city of Mosul north of Baghdad.
Violence perpetrated by ISIS shook a small town near Mosul again Sunday, security officials in Baghdad and the town of Tal Afar told CNN. Several mortar rounds landed on a busy area in the town west of Mosul and killed at least seven and wounded 33 people.
Ethnic Shiite Turkmen live in Tal Afar. Iraqi security forces still maintain a presence there.
Iraq’s leader urges troops to stand ground
Iraqi Prime Minister Nuri al-Maliki ordered Saturday that Iraqi troops stand up to the militants — an order that came after, and in light of, Iraqi security forces completely collapsing when militants assaulted Mosul.
“Samarra will be the starting point, the gathering station of our troops to cleanse every inch that was desecrated by footsteps of those traitors,” al-Maliki said in broadcast remarks.
“They (ISIS) believed that this is the beginning of the end, but we say, this is the beginning of their end, their defeat, because it sparked the passion and determination in all soldiers and officers, and in all Iraqi people,” the prime minister said.
Meanwhile on Sunday CNN Senior International Correspondent Arwa Damon was in the Iraqi Kurdish province of Kirkuk, where last Thursday militants took control of two villages.
She asked the local governor, Dr. Najmaldin Karim, whether the United States should launch airstrikes to help fight back ISIS.
“I think they know how to do it, but blanket bombing is not going to work here,” Karim said, explaining that that approach ignores the fact that ISIS is too blended into the civilian population in Kirkuk and innocent people could die. But there should be targeted bombing in both Iraq and Syria, he said.
“I don’t think anyone is safe from these people,” said Karim.
Partial staff relocation at U.S. Embassy
Between 50 and 100 U.S. Marines and U.S. Army personnel have arrived at the U.S. Embassy in Baghdad, a U.S. official told CNN on Sunday.
A U.S official acknowledged to CNN that the additional embassy security personnel being added are U.S. Marines who specialize in embassy protection during high-threat conditions.
The U.S. invaded Iraq in 2003. American military forces ended their withdrawal from the country in December 2011.
At the time of the U.S. drawdown, Iraq’s leadership had agreed that a residual U.S. military presence was desirable, but the talks broke down over the prickly issue of legal immunity for U.S. troops in Iraq.
The Obama administration had said any deal to keep U.S. troops in Iraq beyond the withdrawal deadline would require a guarantee of legal protection for American soldiers. But the Iraqis refused to agree to that, opening up the prospect of American troops being tried in Iraqi courts and subjected to Iraqi punishment.
This week, President Barack Obama continued to consider options with regard to the situation in Iraq but ruled out sending troops into the country.
On Sunday, U.S. State Department spokeswoman Jen Psaki said that some U.S. security personnel will be added to the staff at the U.S. Embassy in Baghdad and other staff members will be temporarily relocated to consular offices in Basra and Irbil and to the Iraq Support Unit in Amman, Jordan.
A “substantial majority of the U.S. Embassy presence in Iraq will remain in place,” Psaki said in a statement, and “the Embassy will be fully equipped to carry out its national security mission.”
Pentagon Press Secretary Rear Adm. John Kirby said that a “small number of Defense Department personnel” are augmenting State Department security assets in Baghdad. Kirby said that the relocation of some embassy personnel is being done with commercial, charter and State Department aircraft flights.
The U.S. military can airlift people if the State Department asks for that, Kirby said.
While that continues, Iran has recently entered the fray, according to a senior security official in Baghdad who spoke to CNN on Friday. That official said that in recent days, Iran has sent about 500 Iranian Revolutionary Guard troops to fight alongside Iraqi government security forces in Iraq’s Diyala province.
However, Iranian officials, including President Hassan Rouhani, denied reports that some of its elite forces are in Iraq to help bolster al-Maliki, a fellow Shiite.
“If the Iraqi government wants us to help, we will consider it,” Rouhani said, according to an English translation of his remarks Saturday in Farsi by state-run Press TV.
But, he said, “so far they have not asked specifically for help,” and added that Iran could give strategic guidance if requested.
Ex-U.S. ambassador: Kerry should go to Iraq
On Sunday U.S. Sen. Lindsey Graham argued on CNN’s “State of the Union” for more intervention in Iraq.
The South Carolina Republican, a frequent critic of the Obama administration’s approach to foreign policy, called Obama “stubborn-headed,” “delusional” and “detached” over his decision on how to react to the unfolding crisis.
“Time is running out to turn this around,” Graham said. “Get involved with air power. Stop the march toward Baghdad. Deal with Syria. But get a new government [in Iraq] in place as quickly as you can that will bring the Iraqis back together for a counteroffensive.”
Ryan Crocker, the U.S. ambassador to Iraq from 2007 to 2009, told CNN’s Fareed Zakaria on Sunday that he thinks Secretary of State John Kerry should fly to Iraq immediately.
“We need the secretary of state out there in Baghdad right now,” Crocker said. “We need the President on the phone to the Iraqi leadership because the reality is the Iraqis are not in a position … they were not in a position when I was there, they are not in a position now, to work out hard compromises on their own.”
The United States is the “middleman among Sunni, Shia and Kurds,” Crocker said. “Ambassadors can go just so far.”
Now the dean of the George Bush School of Government & Public Service at Texas A&M University, Crocker said he would support “very carefully targeted airstrikes” in conjuction with high-level diplomacy.
“We have got to help the Iraqis come together,” Crocker urged, “in a unified fashion to confront a common threat.”
