A massive gas leak explosion at Venezuela's sprawling Amuay refinery on Aug. 25 killed 48 people and badly damaged 1,600 homes—the worst industrial disaster in the country's history, and the worst refinery accident anywhere on Earth in over a decade. The refinery on the Paraguana Peninsula (see map) is South America's largest and one of the world's largest, run by the state oil company PDVSA. Hundreds of residents of the poor Alí Primera and La Pastora districts near the facility have been left homeless. As the inferno blazed for four days, prompting an exodus from the stricken districts, gangs of looters descended, breaking into the still-standing homes to carry away refrigerators and TV sets. Opposition critics charge that PDVSA failed to carry out maintenance work or improve safety standards following a string of accidents and unplanned outages at the refinery in recent years.

We are heartened to learn that President Obama is staying away from the funeral of Ethiopia's late Prime Minister Meles Zenawi, whose death was announced last week, instead sending a comparatively low-level delegation led by the US ambassador to the United Nations, Susan Rice. (Nazret, Sept. 2) This may indicate a long-overdue distancing of Washington from Meles' odious regime, which we fear may change little with his passing. Meles, who ruled (either as president or prime minister) since 1991, made himself very useful to Washington, "renditioning" terror suspects for brutal "interrogations" in his prisons, and even now providing a military proxy force in Somalia. After Ethiopia invaded Somalia in 2006 (with a US "green light," and probably military advisors), Meles' forces were shortly accused of war crimes by international human rights groups. (NYT, Aug. 16, 2007) Yet this now gets virtually no play in the overwhelmingly and sickeningly favorable media coverage of his legacy—contrary to Julius Ceasar, the evil Meles did is being interred with his bones.

Swiss prosecutors announced Aug. 31 that Erwin Sperisen, former commander of Guatemala's National Civil Police, was arrested in Geneva. The arrest is based on evidence submitted in 2011 by Guatemalan authorities linking Sperisen to extrajudicial killings. Sperisen, 42, holds both Swiss and Guatemalan nationalities; because of his Swiss citizenship he cannot be extradited, but authorities say he will be put on trial in Switzerland. He is accused in at least 10 homicides carried out in Guatemala's prison during his time as police commander from 2004 to 2007, thought to be part of a campaign of "social cleansing."

A Brazilian federal judge in Pará on Aug. 31 agreed to conduct the first trial against members of the former dictatorship for alleged crimes during the military's rule from 1964-1985. The defendants are two retired army reserve members, Col. Sebastiao de Moura and Maj. Licio Maciel, accused of kidnappings during suppression of the guerilla movement in the Araguaia region between 1972 and 1975. The judge agreed with prosecutors that Brazil's 1979 amnesty law, which provides amnesty for members of the government and military alleged to have committed political crimes between 1961 and 1975, does not apply because bodies of the alleged kidnapping victims were never found, and the cases are therefore still technically open.

This week's media headlines about the Syrian crisis have focused on a walk-out by the Syrian delegation at the Non-Aligned Movement summit in Tehran, after Egyptian President Mohamed Morsi called the regime "oppressive"; and a TV interview in which Syrian President Bashar al-Assad said he needed more time to win the war. But the humanitarian situation of hundreds of thousands of people in need of assistance inside Syria has been—as usual, aid workers would say—largely neglected. As violence spreads to previously unaffected areas, internal displacement has reached unprecedented levels. Three million people are in need of food assistance or agricultural support. Many more have been affected by a crumbling economy and a lack of social services, especially health care. Meanwhile, funding for humanitarian aid has not matched the strong rhetoric on Syria in the international community.

US Attorney General Eric Holder announced Aug. 30 that the Department of Justice would close its investigation into the CIA's alleged torture and abuse of detainees, with no criminal charges to be brought as a result of the three-year inquiry. In June 2011 Holder accepted the recommendation of Assistant US Attorney (AUSA) John Durham to open full criminal investigations into the deaths of two individuals while in US custody at overseas locations. The recommendation came during a criminal investigation by Durham that began in August 2009, under which he conducted an inquiry into whether federal laws were violated in connection with the interrogation of specific detainees at overseas locations. The investigation centered primarily on whether any unauthorized interrogation techniques were used by CIA interrogators and whether such techniques could constitute statutory violations of torture.

The US  Department of Defense announced Aug. 29 that the Chief Prosecutor for Military Commissions has filed terrorism charges against a Saudi Guantánamo Bay prisoner accused of plotting with al-Qaeda to blow up oil tankers near Yemen. The detainee, Ahmed al Darbi, has been accused of six offenses under the Military Commissions Act of 2009, including conspiracy, aiding and abetting attacks on civilians, and aiding and abetting terrorism based on his former work as a weapons instructor, contact with Osama bin Laden, and support of bombing civilian oil tankers. According to the statement released by the Pentagon:

Amnesty International reports that 45 families from the Quilombo Pontes community in Pirapemas municipality, in Brazil's northeastern Maranhão state, are being systematically threatened and intimidated by gunmen who are patrolling the area. The gunmen are employed by local ranchers who are trying to push the community off the land. Crops and property belonging to the community have been destroyed, and its members are now struggling to provide food for their families. The Pontes community was officially recognised as a quilombo territory—communities of descendants of escaped slaves—in December 2011, but the authorities have not intervened to guarantee the integrity of their land.
