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)

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).

An apparent chemical attack on the rebel-held town of Khan Shaykhun, Idlib governorate, left at least 80 dead April 4. After a bombing of the town, medics reported a "bloodless massacre," saying that they were treating people with symptoms including fainting, vomiting and foaming at the mouth. The hospital where gas-attack victims were being treated was itself bombed in the immediate aftermath, "bringing down rubble on top of medics as they worked," according to AFP. The opposition-run Health Department in Idlib has provided a list of the names of some 70 dead, with more still being identified. Some of the victims were brought across the border to Turkey for treatment, where several died. Turkish authorities say autopsies revealed evidence of exposure to sarin. The UN Security Council immediately called emergency talks on the attack. On April 4, US warships in the Mediterranean launched 59 Tomahawk cruise missiles at Shayrat air-base outside Homs, from where the Khan Shaykhun attack is said to have been launched. This constituted the first US attack on an Assad regime target throughout the course of the war (not counting last year's accident, immediately apologized for).

A suspected chlorine gas attack on an underground hospital in the rebel-held north of Syria's Hama governorate killed three people and injured dozens on March 25, as Assad regime forces attempt to drive back a rebel offensive in the area, local medical personnel told independent news website Syria Direct. A helicopter dropped a large yellow canister through the concrete roof of the Latamna Surgical Hospital, according to hospital personnel. Chlorine gas was then released, according to the account, spreading throughout the the underground facility. Trapped in the poorly ventilated facility, 35 people were injured—14 of them medical personnel—and three were reportedly killed, including a surgeon. "One of the victims smelled as if he just came out of a swimming pool," said Bilal Abdul Kareem of On the Ground News, reporting from the scene in the aftermath of the attack.

Fierce clashes broke out in Damascus this week after rebel fighters infiltrated the city through tunnels, breaching the regime's security perimeter. The surprise offensive marked a rare advance after months of steady losses for rebel forces across Syria. The Iraqi Shi'ite militia Harakat Hezbollah al-Nujaba announced that it has joined pro-regime forces in the defense of Jobar and Abbasin districts, the outlying areas that came under attack. The militia is said to be effectively led by officers from the Iranian Revolutionary Guard Corps, against ponting  to Tehran's critical role in support of the Bashar Assad regime.

A new Qaeda affiliate in Syria has claimed responsibility for a March 11 double bomb attack targeting Shi'ite pilgrims in Damascus that killed at least 40 Iraqis and wounded 120 more. Footage broadcast by Syrian state TV showed two buses with their windows blown out, the surroundings splattered with blood and littered with lost shoes and clothing. The attack took place near Bab al-Saghir cemetery, named for one of the seven gates of the Old City of Damascus. The pilgrims had arrived to pray at the cemetery after visiting the Sayeda Zeinab shrine outside Damascus, where the grand-daughter of the Prophet Mohammad is said to be buried. In a statement claiming responsibility, Hayat Tahrir al-Sham (Liberation of the Levant Organization) said the attack was "a message to Iran" over its support for the Bashar Assad regime. The group is identified as a breakaway faction of Jabhat Fateh al-Sham (the former Nusra Front) that has maintained ties with al-Qaeda. (BBC News, Reuters)

A militant said to be al-Qaeda's second-in-command was killed by a US drone strike in Syria's Idlib governorate, rebel leaders said Feb. 27. Egypt-born Abu al-Khayr al-Masri (formerly Abdullah Muhammad Rajab Abdel Rahman), the son-in-law of Osama bin Laden, was reportedly a close aide to al-Qaeda's current leader Ayman al-Zawahiri. The drone attack on his vehicle was reported by Hay'at Tahrir al-Sham (Levant Liberation Body, HTS), a newly formed alliance led by Jabhat Fateh al-Sham, the former Nusra Front. (MEE, BBC News, Feb. 27) Two days earlier, HTS claimed responsibility for a suicide blast in Homs that killed a Syrian senior military intelligence official who was reportedly close to dictator Bashar Assad. The official, Gen. Hassan Daabul, was slain along with several others when a suicide bomber penetrated a security complex in the city. An HTS statement said its "inghimasi fighters" were responsible for the raid, and claimed that some 40 personnel were killed. (LWJ, Feb. 25)
