Fierce clashes broke out between Syrian rebel factions and Kurdish fighters in Aleppo province this week, as the Kurdish-led Syrian Democratic Forces (SDF) continue to battle ISIS in Raqqa. Fighting erupted in Derat Ezza in the western Aleppo countryside on June 13, after Kurdish fighters attempted to take a rebel base in the area, opposition media reported. The assault was thwarted after the rebels regained the positions with support from Turkish artillery. At least 32 fighters from Ahrar al-Sham and other rebel groups were reported killed in the clashes, as well as dozens of Kurdish militants. (The New Arab, June 14)

Authorities in Iraq's autonomous Kurdish region have announced that the northern territory will hold a referendum on independence, with a date of Sept. 25 set for the vote. Masoud Barzani, president of the Kurdish Regional Government (KRG), announced the decision on Twitter June 7. The referendum on secession from Iraq will be held in the three governorates that officially make up the Kurdish region (Erbil, Sulaymaniyah and Dohuk) and in the areas disputed by the KRG and Baghdad but currently under Kurdish military control—most notably the potential flashpoint of oil-rich Kirkuk. (Al Jazeera, June 8) (See map)

Several civilians were killed June 8 when US-led air-strikes reportedly targeted Raqqa, the de facto ISIS capital in northern Syria, with white phosphorus—banned by the Geneva Convention as a weapon of war. The reports came both from Syrian state media and local activists on the ground in Raqqa, who posted footage online, showing the skies of above the city lit by a rainfall of glowing ordnance. The report comes as the US-backed Syrian Democratic Forces (SDF) are preparing a final offensive to take Raqqa. (Xinhua) 

Iran's intelligence agency, Ettela'at, has banned publication of a Kurdish language instruction book. The book's authors, in Razawe Khorasan province, report that they have faced threats from the province's security forces—along with the publisher, sellers and readers. The book, Nivisin u Xwendina: Kurdiya Kurmanci, which translates as Reading and Writing: Kurdish Kurmanji, was written by four authors—named as Ebas Ismaeli, Mohammed Taqawi, Mehdi Jaafarzada, and Jawad Aliniya—in the Kurdish dialect of Kurmanji using the Latin alphabet. It was approved for publication last year, but authorities apparently moved to suppress it due to use of the Latin alphabet, which provincial officials said is used by “terrorist groups” and not to the benefit of the Islamic Republic.

Iran's long-dormant militant group, the Party for Free Life in Kurdistan (PJAK), was blamed for a hit-and-run attack on security forces that left two Border Guards dead near the city of Urmieh (also rendered Urmiya) on May 28. Commander of the Iranian Border Guards, Qassem Rezayee, responded by warning Turkey to take measures against the movement of "terrorist" groups along the frontier. He said that Iranian authorities "consider Turkey responsible, and the country should account for this act.... The Iranian forces will certainly give a crushing response to these moves." Iran's Foreign Ministry has also lodged a protest with Turkey over the incident. Turkey recently started construction of a security wall on its border with Iran to prevent infiration of Kurdish militants. (Press TV, May 29; Xinhua, Kurdistan24, May 28; Kurdistan24, May 14)

As the votes came in on Iran's May 19 elections, populist hardliner Ebrahim Raeesi reluctantly accepted incumbent president Hassan Rouhani's 57% victory, after a bitter campaign. The rhetoric was so heated that a week before the poll, Rouhani even challenged Raeesi, a sitting judge, to issue an arrest warrant for him. Media organizations affiliated with Iran's hardliners, like Tasnim and Fars, went to bat for Raeesi, publishing rumors about the death of Rouhani's son 20 years ago, alleging the apparent suicide was carried out with the father's personal firearm and calling for a new investigation. Meanwhile, Basiji pro-regime militia forces (which played a critical role in violence following the disputed 2009 elections) attacked a number of Rouhani campaign offices in Tehran, Mashhad, Qazvin, Babolsar and Isfahan.

In their White House meeting May 16, President Trump and his Turkish counterpart Recep Tayyip Erdogan of course pledged cooperation in the fight against terrorism. But what is signficant is that Trump, probably none too sophistcated about the complexities of factional politics in the region, was sure to mention the Kurdistan Workers Party (PKK) by name: "We support Turkey in the first fight against terror and terror groups like ISIS and the PKK, and ensure they have no safe quarter. We also appreciate Turkey's leadership in seeking an end to the horrific killing in Syria."

President Donald Trump on May 9 announced approval of a plan to arm the Syrian Democratic Forces (SDF), the anti-ISIS coalition led by the Rojava Kurds. The aid—including heavy machine guns, mortars, anti-tank weapons, armored cars and engineering equipment—will boost the prowess of the People's Protection Units (YPG), territorial defense militia of the Rojava autonomous zone and the central pillar of the SDF. "The Syrian Democratic Forces, partnered with enabling support from US and coalition forces, are the only force on the ground that can successfully seize Raqqa in the near future," said a Pentagon statement. The move is being taken over strenuous Turkish objections to arming the Syrian Kurds, and will certainly be a contentious point when President Recep Tayyip Erdogan meets with Trump in Washington next week. (ANF, NYT, May 9)
