Commemorations were held in Cuzco, Peru, marking 236 years since claimant to the Inca throne Túpac Amaru II launched his indigenous uprising on Nov. 4, 1780. The ceremony, at the highland city's iconic Túpac Amaru Plaza, was attended by the fabled leader's direct descendant, Pedro Noguera Prada, who came from his home in France for the event. Loaning credence to the claim of royal Inca descent, Noguera asserted that contrary to most historical accounts, his ancestor's given name was not José Gabriel Condocarqui but José Gabriel Túpac Amaru Noguera. He asserted that the leader's 1760 marriage certificate, from when he wedded his later co-revolutionist Micaela Bastidas Puyucahua, remains on file in Canchis municipality, and shows this correct name.

For the first time in history, governments around the world have agreed to legally binding limits on global temperature rises as the Paris Agreement (PDF)  on climate change became effective on Nov. 4. All governments that have ratified the accord are now legally obligated to cap global warming levels at 2 C above pre-industrial levels—regarded as a limit of safety by scientists. But environmentalists and other groups have said the agreement may not be enough. According to Asad Rehman of Friends of the Earth: "The Paris agreement is a major step in the right direction, but it falls a long way short of the giant leap needed to tackle climate change. Far tougher action is needed to rapidly slash emissions." Greenpeace also agreed that while the agreement is a major step forward, it needs stronger force. Andrew Norton, director of the International Institute for Environment and Development, further pointed out that governments would need to take measures to ensure that the poorest and most vulnerable countries get adequate financing to tackle climate change problems..

Turkey's Interior Ministry confirmed Nov. 3 that 11 lawmakers with the leftist and Kuridish-led Peoples' Democratic Party (HDP) lawmakers have been detained by police in operations across the country, ostensibly as part of a terrorism investigation. Those detained include HDP co-chairs Selahattin Demirtas and Figen Yuksekdag. The arrests come as President Recep Tayyip Erdogan is seizing draconian powers in the wake of July's attempted coup. Hours after the arrests, a bomb attack outside a police station in Diyarbakir left eight dead and over 100 wounded. As in previous recent terror attacks in Turkey, authorities initially blamed the leftist Kurdish guerillas of the PKK, but it was subsequently claimed by ISIS.

Russian President Vladimir Putin has issued an ultimatum to the defenders of Aleppo's rebel-held east that they abandon the city by Friday Oct. 4. The rebel leaders pledge defiance, saying that promised safe passages out of besieged areas are a trap. "This is completely out of the question. We will not give up the city of Aleppo to the Russians and we won't surrender," Zakaria Malahifji, of the Fastaqim rebel group, told Reuters, denying that there are safe exit corridors. "It's not true. Civilians and fighters are not leaving. Civilians are afraid of the regime, they don't trust it. And the fighters are not surrendering." (The Guardian, Al Jazeera) A Russian military fleet is meanwhile making its way to Syria, signaling an imminent escalation in the ongoing aerial assault on Aleppo. There has been some controversy about the fleet's refueling stops along the way. While NATO member Spain has allowed Russian warships en route to Syria to resupply at its port of Ceuta before, this time international pressure led Moscow to withdraw its request for a stop there. (World Post, The Local, Spain) The Royal Navy, which monitored the fleet's passage through the English Channel, says it includes the aircraft carrier Admiral Kuznetsov as well as three submarines (two nuclear-powered) armed with cruise missiles.

Civilians have been trapped for months in a neighborhood of the eastern Libyan city of Benghazi, amid fighting between the Libyan National Army (LNA) and Islamist militias that form the Benghazi Revolutionary Shura Council (BRSC). Human Rights Watch called for all sides to the conflict to allow all civilians to leave the Ganfouda district, and allow for the safe passage of humanitarian aid into the neighborhood. Ganfouda is one of the few remaining holdouts of militant Islamist groups in Benghazi. The LNA, which has Ganfouda under siege, has said it will not allow any evacuation of males between ages 15 and 65, and has set a series of other conditions. The Islamist coalition controlling the neighborhood has also set conditions for evacuation of civilians.

The Philippines' ultra-hardline President Rodrigo Duterte arrived in China Oct. 18 for a high-profile visit that western media accounts are portraying as a tilt away from the United States. Washington has historically been the Philippines' imperial patron, providing investment and military aid—but relations are now strained over Duterte's murderous anti-drug crackdown, which is believed to have claimed 3,000 lives. Arriving in Beijing, Duterte blasted Washington and the European Union for their criticisms of his lawless crackdown, and praised his hosts for giving him free rein. "China is the only country to come out freely and [make] a firm statement that they are supporting the fight against drugs in my country," Duterte told Chinese state news agency Xinhua in a comment picked up by the Philippine Star. "The other countries, United States, EU, instead of helping us, they know that we are short of money... all they had to do was to criticize. China never criticized."

A federal judge has rejected (PDF) the New York Police Department's proposed settlement of a lawsuit accusing the department of improperly monitoring the city's Muslim community. Following the September 11 attacks, the NYPD has reportedly used undercover cops to monitor Muslim neighborhoods, organizations and mosques in the name of national security. In January, a settlement was reached, calling for a stricter modification of the police surveillance "Handschu" guidelines (PDF) and a civilian representative installed for five years to ensure that the NYPD complies. The NYPD declined to accept all proposed modifications yet acquiesced to the establishment of a civilian representative. Nevertheless, US District Judge Charles Haight rejected the proposed settlement, stating that it does not sufficiently protect the constitutional rights of Muslim citizens. Haight suggested that the NYPD further clarify the representative's role, and take additional measures to ensure guideline compliance such as requiring reporting to the court. While expressing disappointment in the ruling, the New York City law department stated its intention to address the judge's concerns.

A growing wave of paramilitary terror is reported from the remote and rugged Sierra Tarahumara in northern Mexico's Chihuahua state—the country's prime opium and cannabis cultivation zone. Local residents at the hamlet of El Largo Maderal, in the backwoods of Madera municipality, on Oct. 14 issued an urgent alert to the authorities and media over ongoing attacks by narco-gunmen, leaving at least two campesinos dead over the past weeks. The Chihuahua state prosecutor, or Fiscalía General, meanwhile reported a highway attack at nearby Rancho Las Pomas, where a local narco-jefe identified only as "El Nacho" was killed along with two henchmen—their car shot up and then set aflame.
