IRAQ and SYRIA

Syria peace talks. Chief Syrian opposition negotiator Mohammad Alloush resigned from the UN-backed peace talks on Sunday, citing the international community’s failure to progress toward ending the conflict in Syria, and ongoing hostilities on the part of the regime. The move does not bode well for the success of the talks, report Dana Ballout and Raja Abdulrahim. [Wall Street Journal]

Retaking Fallujah. Iraqi ground forces backed by US-led military aircraft are meeting stiff resistance in their attempt to drive the Islamic State from the Iraqi city of Fallujah that kicked off yesterday. Islamic State fighters used tunnels, car bombs, and snipers to engage Iraqi troops in a four-hour battle this morning, according to the AP. For the past week, Iraqi forces have been reclaiming districts on the outskirts of the city, creating a “ring of steel” around the Islamic State fighters who retain control of the city itself, according to the most recent reports.

Regaining Fallujah would be a “psychological boost” for Iraq’s so-far unproven military, writes Rebecca Collard in the Financial Times. There are reportedly fewer than a thousand Islamic State fighters in the city, while Iraqi soldiers and their allies surrounding them number in the thousands. Even so, the battle “will not be easy:” The Islamic State has an advantageous position, and there are tens of thousands of civilians still within the city.

The composition of the forces – militias bound to the Shia regime and close to its allies in Damascus – fighting Islamic State in Fallujah and in Raqqa, Syria, both Sunni cities, is “intensifying sectarian and ethnic tensions” risks helping the Islamic State “gain legitimacy as a defender of Sunnis,” suggests Hassan Hassan. [Financial Times]

Russia has reportedly drafted a constitution for Syria, with the “blessing” of the US. Leaked extracts indicate that the constitution promises a future that is “molded out of the will and interests of the Syrian regime and its allies” and does little to “disincentivize violence” or “create the basis for a post-conflict political system that enjoys the support of and legitimacy by Syrians,” reports Al Jazeera‘s Samer Abboud. The Syrian presidency denies the existence of the constitution.

The Kurdish offensive against the Islamic State in both Syria and Iraq is being supported by elite US soldiers. But how far will the Kurds go, and with what consequences, asks Florian Neuhof in The Daily Beast. The long-term goal, he reports, is to carve out a larger Kurdistan from a “disintegrating Iraq.”

PAKISTAN, AFGHANISTAN and THE TALIBAN

The Taliban captured almost 200 bus and vehicle passengers near Kunduz city, Afghanistan, this morning, though the precise details vary from source to source. It appears that the militants abducted the travelers at a checkpoint set up to stop the vehicles. The fate of the hostages remains unclear. [Khaama Press]

Over 50 Afghan police officers have been killed in and around Helmand over the weekend and on Monday, as the Taliban embarked on its first major offensive since the accession of new leader Mullah Haibatullah Akhunzada. [Al Jazeera]

The brother of a Pakistani man killed alongside ex-Taliban leader Akhtar Mohammad Mansour in a US drone strike is seeking a police investigation into his brother’s death. Muhammed Azam was driving Mansour in Pakistan’s Noshki district on May 21 when a US drone strike killed them. Azam’s brother claims he was simply a taxi driver with no connection to the Taliban. [Washington Post]

GUANTANAMO BAY

The Pentagon’s top two officials issued a statement supporting the independence of Guantánamo Bay’s war court on Friday, a response to the 9/11 trial judge’s ruling that a ban on physical contact between female guards and detainees would be extended to October 28 in light of several instances of apparent “unlawful influence” over the court by the officials, and his invitation to “take appropriate action to absolve any taint” caused by their criticism of the temporary restraining order. [Miami Herald’s Carol Rosenberg]

Claims that Guantánamo Bay’s notorious Camp 7 is falling apart were a “big mistake,” according to the detention center’s current commander. Billions of dollars were requested to refurbish the prison, following a report which officials are now saying was “not based on sound engineering analysis.” Camp 7 houses prisoners currently involved in the 9/11 pretrial hearings, including alleged 9/11 mastermind Khalid Sheik Mohammed.

OTHER DEVELOPMENTS

Former NSA contractor Edward Snowden performed a “public service” when he engineered “one of the biggest document leaks in American history” in June 2013, because it sparked a debate over government surveillance techniques, former US attorney general Eric Holder has told “The Axe Files” host David Axelrod.
