It seems to have finally come to open war between the Rojava Kurds and the Turkish intervention force in Syria. The People's Protection Units (YPG) and allied factions of the Syrian Democratic Forces (SDF) have sent reinforcements to the northern countryside of Aleppo governorate to impede the Turkish progress towards Afrin district. "The YPG and SDF today deployed more forces and armored vehicles in northern Aleppo," a YPG officer told the independent Kurdish ARA News June 29. "The Kurdish people in Afrin region have suffered a lot under heavy bombardment by Turkey and allied Islamists." Clashes are already reported bewteen the two sides. But in another sign of shifting alliances, the Assad regime is reported to have sent troops to block the way of the YPG-SDF reinforcements. This is clear evidence that the tactical alliance between the Kurds and Assad is now severely strained if not entirely broken. It may even indicate Assad has acquiesced in establishment of a Turkish buffer zone in northern Syria under Russian pressure. (More at Zaman al-wsl, June 28; ANF, June 22)

The US Supreme Court on June 26 agreed to review (PDF) the Trump administration's travel ban, partially lifting the temporary injunction that had blocked the ban's enforcement. The administration sought review of decisions issued by the US Courts of Appeal for the Fourth and Ninth circuits last month. The Supreme Court's order permits execution of the travel ban, but it "may not be enforced against an individual seeking admission as a refugee who can credibly claim a bona fide relationship with a person or entity in the United States."

Under the slogan "The People Are Stronger Than You," thousands of local residents have repeatedly taken to the streets of Ma'arat al-Numan, a town in Syria's northwestern Idlib governorate, to oppose the rule of jihadist forces that have seized control there. The protests broke out after the Qaeda-affiliated militia that controls the town, Hayat Tahrir a-Sham (HTS, an offshoot of the Nusra Front) raided the local headquarters of the Free Syrian Army's Division 13, killing and detaining several FSA fighters on June 8. The biggest reported protest came on June 11, when thousands of residents and civil resistance activists waving Free Syrian flags mobilized to demand the release of the detained fighters.  "We will continue to resist [HTS] in the same way that we peacefully resisted the Syrian regime, and endured its crackdown on protests," Khaled al-Hamid, a 22-year-old protest organizer, told independent news site Syria Deeply.

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)

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) 

In a strange imbroglio, Saudi Arabia, Egypt, the United Arab Emirates, Bahrain, Yemen and the Maldives on June 5 all announced that they are breaking off diplomatic relations with Qatar, accusing it of supporting terrorism. All but Egypt also cut off all travel links with the country. The Saudi statement accused Qatar of "adopting various terrorist and sectarian groups aimed at destabilizing the region including the Muslim Brotherhood Group, Daesh (ISIS) and Al-Qaeda, " and of "supporting the activities of Iranian-backed terrorist groups" in Saudi Arabia and Bahrain. Days earlier, Saudi Arabia, Egypt, the UAE and Bahrain all blocked Al Jazeera and other Qatar-based news websites after Qatari emir Sheikh Tamim bin Hamad al-Thani was quoted as saying "There is no reason behind Arabs' hostility to Iran"—an obvious reference to the Saudis and Bahrain. Qatar quickly responded that the comment had been "fabricated" when hackers took control of the official Qatar News Agency website (which appears to still be down, although the QNA Twitter account is up).

President Trump announced his decision June 1 to pull the United States out of the Paris Agreement on Climate, signed by 195 nations and formally joined by 147, including the US. The United States now joins Syria and Nicaragua as the only nations in the world not supporting the accord. Nicaragua, it should be noted, failed to join because the terms of the accord are not binding, and it was therefore considered too weak. Syria is consumed by internal war, and was iced from the negotiations by restrictions on its envoys traveling to the talks. The agreement, which seeks to limit global warming to 2°C above pre-industrial levels, came into force on Nov. 4, 2016, just days before Trump was elected. Each country sets its own commitments under the accord. The United States, second-largest emitter on the planet after China, had committed to reducing its carbon emissions by 26 to 28% below 2005 levels by 2025. It also commited up to $3 billion in aid for poorer countries to address climate change by 2020. (ENS, June 2; NYT, June 1; WP, May 31)

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)
