At least 13 inmates were killed and some 30 injured in a clash between rival gangs Oct. 10 at Pedrinhas prison in São Luis, in Brazil's northeastern state of Maranhão. Authorities said violence broke out after guards discovered inmates digging an escape tunnel. The inmates fought the attacking guards and started a fire, as members of rival gangs took advantage of the confusion to settle scores. Then, as news of the conflagration broke, relatives of inmates gathered outside the prison, demanding information. When this was not forthcoming, they began to throw stones at the guards, took over a roadway, and set several buses on fire.

At least three are dead in clashes as opposition parties attempt to enforce a three-day general strike in Bangladesh, aimed at bringing down the government. All public gatherings have been banned in the main cities of Dhaka and Chittagong, but protesters have repeatedly defied the decree, leading to street-fighting with police and government supporters. The opposition Bangladesh Nationalist Party (BNP) and Jamaat-e-Islam are demanding Prime Minister Sheikh Hasina install a caretaker administration to oversee the January general election. Hasina, who heads the ruling Awami League, rejects the demand. Tensions have been growing for months between the secular but increasingly authoritarian Awami League and a radicalizing Islamist opposition.

The lawyer for five Guantánamo Bay prisoners charged with plotting the September 11 attacks has asked President Barack Obama to declassify the CIA interrogation program that allegedly subjected prisoners to torture. The letter (PDF), made public on Oct. 25, calls upon Obama to make the details of the CIA's rendition, detention and interrogation (RDI) program public. This program has been linked to certain interrogation techniques that have been said constitute torture. In the letter, the lawyer for the defendants argues:

Sixteen accused militants were hanged Oct. 26 at Zahedan prison in Iran's Sistan-Baluchistan province, on the Pakistani border—in apparent retaliation for the deaths of 14 border guards in an ambush just the night before. Officials blamed the attack outside Saravan on "anti-revolution guerrillas"—an apparent reference to the armed Baluch Sunni group Jundallah. But loca parialment member Hedayatollah Mirmoradzehi named a new Jaish al-Adl, or Army of Justice, as responsible for the attack. The BBC's Kasra Najisaid the mass execution "smacks of revenge killing by the judiciary."

The US Court of Appeals for the Ninth Circuit ruled (PDF) Oct. 7 that the Detainee Treatment Act prevents the court from having jurisdiction over a former Guantánamo Bay detainee's lawsuit for damages. Adel Hassan Hamad, a Sudanese national, was captured in 2002 and transferred to Guantánamo prior to an agreement an agreement to transfer him to Sudan in 2007. Hamad states that that he was wrongfully detained and subjected to torture while held and filed the lawsuit to seek damages stemming from his detention. The Ninth Circuit vacated the district court's orders and directed the district court to render a judgment dismissing the lawsuit. The US Court of Appeals for the District of Columbia Circuit in 2001 ruled that Hamad could not continue to litigate a habeas corpus petition and refused to order the government to rescind their designations as "enemy combatants."

The US Court of Appeals for the Second Circuit on Oct. 24 upheld the conviction (PDF) of ex-Guantánamo detainee Ahmed Khalfan Ghailani in the 1998 bombings of two US embassies in Africa. Ghailani had appealed his conviction on the premise that his constitutional rights to a speedy trial had been violated by his lengthy detainment and interrogation by the US Central Intelligence Agency (CIA). Although the interrogation techniques that were used remain classified, the CIA has justified this practice as an effort to gain "critical, real-time intelligence about terrorist networks and plots." This appeal provided the court an opportunity to consider, and ultimately provide support for, the legal implications of US efforts to gain intelligence from terrorism suspects before prosecuting them. Ghailani's lawyer has said that he will appeal the case to the Supreme Court.

About 30 aides to Moammar Qaddafi, including his son Saif al-Islam Qaddafi, were indicted Oct. 24 by a Libyan court for a list of offenses allegedly committed during the 2011 revolt in the country. The charges levied against them include murder, kidnapping, complicity in incitement to rape, plunder, sabotage, embezzlement of public funds and acts harmful to national unity. Although less than half of the defendants appeared in court for the indictment hearing on Thursday, all defendants must be present at the trial hearing, the date of which has not yet been set. The trial will be one of the most high-profile in the country's history, with defendants including senior officials such as former intelligence chief Abdullah al-Senussi and Qaddafi's last prime minister Baghdadi al-Mahmudi.

Renowned Mexican investigative journalist Anabel Hernández, author of Narcoland: The Mexican Drug Lords and Their Godfathers, has been receiving police protection since her reportage outed top figures in the country's security apparatus as drug cartel collaborators—resulting in threats on her life.
