Moscow's military intervention in Syria took a sobering turn this weekend as Turkey scrambled fighter jets, accusing Russian warplanes of violating its air space. Turkey has summoned the Russian ambassador over the matter, and NATO condemned the incursions as an "extreme danger." (Al Jazeera, CNN, Daily Sabah) Apart from the obvious dangers to world peace (such as it is), this development holds grim implications for the Syrian Kurds—the most effective military force on the ground against ISIS. Turkey, afraid that a Kurdish autonomous zone on its southern border will inspire its own Kurdish population to rise up, has been cynically labelling the anti-ISIS Syrian Kurds as "terrorists," and seeking to establish a military "buffer zone" in Kurdish territory in norther Syria. Since Turkey and Russia are bitter regional rivals, Moscow's intervention risks drawing the Kurds into the geopolitical game.

The Rojava Kurds of northern Syria continue to be punished for their success against ISIS. Their ground offensive has throughout the summer been driving ISIS back towards Raqqa, the "Islamic State" capital. The autonomous Rojava cantons, previously cut off from each other by areas of ISIS control, are now linked by swaths of liberated territory. This dramatically contrasts recent ISIS gains in central Syria. Now Middle East Eye reports that the Rojava Kurds's YPG militia is advancing on Jarabulus, the last ISIS-controlled town on the Turkish border. The account cites the widespread perception among the Kurds that the Turkish government has been conniving with ISIS: "Taking the Jarabulus crossing would be a major advance for the YPG since they are convinced that IS gets supplies of recruits and weaponry through Turkey. YPG officials claim the crossing is open, and IS has no need for smugglers or breaks in the border fence." In a particularly sinister game, Ankara has collaborated with ISIS even while equating ISIS and the anti-ISIS YPG as both "terrorist" (sic!). Such propaganda will doubtless be escalated if the entire Syrian border with Turkey falls under YPG control, raising fears in Ankara of an independent Kurdish state.

Street clashes continue in the Sur district of the largely Kurdish city of Diyarbakır, which has for days been under siege by Turkish security forces. On Sept. 13, Diyarbakır's governor declared a 24-hour indefinite curfew in the district, but it was widely defied as angry protesters continued to fill the streets. Police threatened to shoot curfew violators, and have opened fire on protests—thus far resulting in no casualties, apparently. "Everywhere is Sur, everywhere resistance," crowds chant. Protests have spread to the nearby Koşuyolu Park, were demonstrators are rallying around the local offices of Democratic Society Congress (DTK). Police are trying to round up leaders of the PKK-affiliated Patriotic Revolutionary Youth Movement (YDG-H), who they say are behind the uprising. The Democratic Regions Party (DBP) has called on all residents of Diyarbakır to join the protests and converge on Sur district. Apparently fearing escalation, the city's government lifted the curfew after one day. (JINHA, Today's Zaman, Sept. 14)

ISIS fighters have seized the last oil-field still under the control of the Assad regime after several days of fighting, according to the Syrian Observatory for Human Rights. The Jazal field, with a production capacity of 2,500 barrels per day, has changed hands before, with ISIS briefly capturing it in June before regime forces retook it. The nearby town of Jazal has also been occupied by ISIS. Of course, the Assad regime has directly abetted the rise of ISIS by buying their oil, so now we will find out if the Islamic State will cut off Damascus and gear up for a final offensive—or if the relationship between the supposed enemies is in fact too incestuous for that. And Turkey has, up to now at least, also been a ready market for ISIS oil... A relationship also now being put to the test, as Ankara as ostensibly joined the US-led anti-ISIS coalition—despite having connived with ISIS against the Kurdish forces.

The Turkish military carried out air-strikes against PKK positions Sept. 7, a day after a guerilla attack on a military convoy near Daglica, Hakkari province, in which either 16 or 31 soldiers were killed (whether you believe the government or the PKK). Turkish fighter jets have struck 23 targets in the area, in what the military called a "heavy air campaign." (NYT, AP, BGN, Sept. 7) There is no word yet on casualties from the air-strikes, which are presumably on villages thought to be PKK strongholds. But world leaders and media are largely giving the Turkish state a free ride in its efforts to cast its campaign of state terror in "anti-terrorist" terms. Turkey will be "cleaned of terrorists no matter what happens," Prime Minister Ahmet Davutoglu boasted to the official Anadolu news agency. Daily Sabah boasts in its headline, "World stands by Turkey against terrorism," noting that the French Foreign Ministry denounced the "terrorist attack claimed by the PKK against military vehicles in the southeast of Turkey" and pledged "solidarity with the Turkish authorities." But the ongoing attacks on Kurdish civilians by Turkish state forces are conveniently invisible to the outside world...

Syrian civilians are facing war crimes and crimes against humanity with "no end in sight," a group of UN human rights experts finds. The Independent International Commission of Inquiry on the Syrian Arab Republic issued its latest report (PDF) on the civil war in Syria Sept. 3. Paulo Sergio Pinheiro, chair of the UN investigative panel, stated to members of the Associated Press that the Islamic State (IS) seems  to be "desperate, because they are losing ground." According to the report, IS suffered significant losses to the Kurdish armed group, the People's Protection Units (YPG), and has resorted to using suicide car-bombs and hit-and-run tactics. US intelligence agencies seem to disagree with Pinheiro, as the CIA and other agencies announced in July that their assessments show IS is "fundamentally no weaker than it was when the US-led bombing campaign began a year ago."

Hungary's increasingly fascistic Prime Minister Viktor Orban, in Brussels to pitch the EU on his tough new anti-immigrant policy, issued a warning to Syrian refugees: stay out of his country. In a statement all the more sickening for being veiled in an Orwellian cloak of "morality" and "humanitarian" concern, he told reporters: "The moral, human thing is to make clear 'please don't come! Why you have to go from Turkey to Europe? Turkey is a safe country. Stay there, it's risky to come! We can't guarantee that you will be accepted here.'" And of course by "can't guarantee that you will be accepted," what he really means is "we will not accept you." Orban hopes to push through his new anti-immigrant law by Sept. 15, making it a criminal offense to cross the Hungarian border without proper documentation, or to cause damage to the new "security fence" being built along the 175-kilometer frontier with Serbia. (Euronews)

Authorities in Turkey's eastern Muş province have launched an investigation into the distribution of photos on social media showing the dead and mutilated body of a woman believed to be a militant of the Kurdistan Workers' Party (PKK). (See map) The governor's office confirmed that the woman in the picture was PKK militant Kevser Eltürk AKA Ekin Wan, who was killed in a clash with Turkish security forces on Aug. 10 in Muş' Varto district. The picture shows a naked woman, apparently dead, lying on the ground with bruises and blood visible on her body. Three men, whose faces are not seen, are seen standing near the body. Eltürk appeared to have finally been strangled, according to Democratic Regions' Party (DBP) regional co-chair Hamiyet Şahin, who washed the militant's body in preparation for burial. A protest march over the incident Aug. 16 was followed by a sit-in protest organized by the DBP that drew Peoples' Democratic Party (HDP) deputies Gülser Yıldırım and Enise Güneyli.
