A video posted by ISIS Aug. 28 purports to show militants beheading a Kurdish Peshmerga fighter in Mosul. The video, posted to YouTube, says the killing is a warning to the Kurdistan Regional Government to end its alliance with the United States. In the footage, 14 other Peshmerga fighters are shown wearing orange prison suits, urging Kurds to reject their pact with the US against the Islamic State. Three armed militants stand behind one alleged Peshmerga captive near Mosul's iconic mosque, one of them brandishing a knife as he threatens that the rest of the Peshmerga troops will die if the KRG-US alliance does not come to an end. YouTube immediately removed the video. The video release comes as Peshmerga forces have taken several villages from ISIS in the Zumar area (Nineveh). (Rudaw)

ISIS supporters posted photos to Twitter of fighters from the militant group in control of Russian Sukhoi warplanes, as well as missiles and tanks seized after the jihadists overran the Syrian air base of Tabaqa. The fall of the base gives ISIS full control over Raqqa governorate. Syrian government forces withdrew from the base after a battle that lasted five days, leaving 195 government troops and 346 ISIS fighters dead. The images appear to contradict the Damascus governemnt's claim that all aircraft had been evacuated form the base before it fell. (IraqiNews.com, Aug. 28; AP, Aug. 25)

Thousands of Yazidi refugees who have fled the Sinjar region of northern Iraq have been denied entry into Turkey by military forces. The refugees, many of whom managed to flee north through the civilian corridors established by the PKK-aligned YPG militia, have been left waiting on the Turkish border near the Roboski crossing. Turkish soldiers have met any attempts to cross the border with force, according to a report in Turkey's Özgür Gündem. They are struggling to protect their children and ill from the sun under the shade of rocks and the sparse trees. They eat whatever food they can find and cooking is done in empty oil containers or cans. Many mothers have been forced to give birth on the road and some have declined to give their new children names out of fear for their future. (Rojava Report)

A suicide bomber detonated his explosives inside a husseiniya, or Shi'ite mosque, in central Baghdad on Aug. 25, leaving at least 13 dead. Three were killed and several wounded in two other car bombings elsewhere in Baghdad. Another 23 were killed in car bombings at the Shi'ite holy city of Karbala and nearby al-Hilla. (IraqiNews.com, IraqiNews.com, IraqiNews.com, BBC News, NYT) A Kurdish MP in Iraq's parliament called on new Prime Minister Haidar Abadi to either arm the Kurdistan Regional Government or permit it to seek arms elsewhere. "It is crucial for the new government of Baghdad to give weapons to Peshmerga forces and train them as part of the Iraqi army or allow the Kurdistan Region to be able to buy weapons from other countries," said MP Shwan Mohammed Taha. "Today, Peshmerga forces protect 20% of Iraq's border and our demands are not unconstitutional. Putting Peshmerga forces in the security system of Iraq is a constitutional demand."

The Yazidi miltia that has been formed to help Peshmerga forces liberate Sinjar from ISIS is being armed by the Kurdistan Regional Government. The militia's commander, Qassim Shashou, told the independent Kurdish agency BasNews that he hopes to receive heavy artillery has said had been promised by the KRG. "We are looking forward to receiving the weapons which will be vital in our fight against IS. After we free Sinjar, we can return to our homes with our head held high," said Shashou. (BasNews) Qasim Shesho, another member of the militia, urged his fellow Yazidis to stand and fight rather than flee Iraq. "Those who urge Yezidis to leave for Europe have no integrity or conviction," he told Rudaw agency. "We ask these people [who have left] to come and defend their land and return to Shingal,"* he told Rudaw in an interview. "I have German citizenship and could leave today, but it would be a disgrace to abandon my land." The militia, said number 2,000, is also coordinating with the PKK-aligned People's Protection Units (YPG) in the battle for Sinjar. They are hoping to protect Yazidi holy places in the mountains, such as the shrine to 13th century saint Sharafaddin, before they are desecrated or destroyed by ISIS. (Rudaw)

Gunmen opened fire inside a Sunni mosque in Iraq's eastern Diyala governorate, killing at least 68 people, Aug. 22. A suicide bomber broke into the Musab bin Omair Mosque during Friday prayers in the village of Imam Wais and detonated his explosives. He was followed by gunmen, who rushed in and opened fire on the worshippers. Initial reports blamed ISIS in the massacre, but reports later in the day blamed an unnamed Shi'ite militia, suggesting it was retaliation for a roadside bomb attack at a recruitment event organized by the militia.

Boy, did we ever call this one. Contrary to the prevailing leftist conspiracy theory that the US was backing ISIS against Assad, we predicted earlier this year that the US would soon intervene in Syria against al-Qaeda and its offshoots such as ISIS. Today, the New York Times reports the comments of  Gen. Martin E. Dempsey, chair of the Joint Chiefs of Staff, that ISIS cannot be defeated unless the US or its partners take them on in Syria. "This is an organization that has an apocalyptic end-of-days strategic vision that will eventually have to be defeated," Dempsey said. "Can they be defeated without addressing that part of the organization that resides in Syria? The answer is no." Dempsey and Defense Secretary Chuck Hagel, who both spoke at a Pentagon press conference, stopped short of saying air-strikes on Syria are planned, but the comments were obviously intended to float the idea.
