The American Civil Liberties Union is offering to help University of Pittsburgh students who were arrested during the Group of 20 economic summit in Pittsburgh—some of whom say they weren't even protesting. ACLU attorneys made the offer at a rally Oct. 1 attended by some 150. They say police conducted unlawful mass arrests and used excessive force.

Internationally-known Mexican environmentalist and forest defender Felipe Arreaga was killed Sept. 16, while driving his ATV in Petatlan, Guerrero. The longtime campesino leader was struck by a mini-bus and died a few hours later in a hospital in nearby Zihuatanejo. Although Petatlan is the site of a military base, it lacks civilian medical facilities capable of handling serious injuries. The driver of the mini-bus fled the scene of the crash, and many circumstances of the incident are still unclear.

Taking a cue from Argentina's Mothers of Plaza de Mayo, relatives of disappeared persons staged a loud demonstration in Tijuana on Sept. 25.

In an action that attracted public attention, relatives of the disappeared plastered pictures of their loved ones on the exterior of the government offices.

The African Union, European Union and United Nations Sept. 29 strongly rebuked the Guinean army's repression of a protest in the capital, Conakry, in which 157 people are said to have been killed.

The military crackdown on junta opponents killed 157, the Guinean Human Rights Organization said, citing army and hospital sources.

Nearly 30 heads of state attended the Second Africa-South America Summit, a Sept. 26-27 meeting of representatives of 61 nations on Isla Margarita, Venezuela, intended to increase trade and economic development cooperation between the two regions. The first summit was held in Abuja, the capital of Nigeria, in November 2006. "North-North and North-South summits have been held," Venezuelan Deputy Foreign Minister for Africa, Reinaldo Bolívar, told the Inter Press Service (IPS), "but apart from the Summits of South American-Arab Countries in 2005 and 2009, the Africa-South America meetings are the only South-South summits taking place in the world."

Spanish police arrested former Argentine military pilot Juan Alberto Poch on Sept. 21 in Valencia on charges by Argentine courts that he flew some of the "death flights" in which as many as 1,000 opponents of Argentina's 1976-1983 military dictatorship were thrown from planes into the Atlantic while drugged. When he was arrested, Poch, a dual national of Argentina and the Netherlands, was working as a pilot for Transavia, a low-cost airline owned by KLM and Air France. He was arrested while at the controls of a plane in Manises airport, about to fly a holiday group from Valencia to Amsterdam. Spanish police said Poch is named in four separate investigations in Argentina; he will face an extradition tribunal to determine whether he will be sent to Argentina. (The Guardian, UK, Sept. 23)

On Sept. 23 Chevron Corp., the second-largest US oil company, announced that it had asked the Permanent Court of Arbitration in The Hague to shift responsibility to Ecuador for paying any money that Amazon Basin residents might win in a lawsuit over environmental damage from oil operations. The suit, brought by indigenous Ecuadorians 16 years ago, could result in an award of $27 billion. If Chevron wins in the arbitration court, Ecuador will have to pay the damages, according to Barry Appleton, an attorney who has represented companies in similar cases. "Judgments from this panel are enforceable around the world," he said.

During a meeting in Brasilia on Sept. 17, Brazilian foreign minister Celso Amorim and US commerce representative Ronald Kirk ratified a plan to allow Brazilian companies operating in Haiti to export products to the US without paying customs fees. This would be done through an extension of two US trade acts ostensibly aiding Haitian industries: the Haitian Hemispheric Opportunity Through Partnership Encouragement (HOPE) Act of 2006 and the HOPE 2 Act of 2008. Amorim told the Chinese news agency Xinhua that the initiative's goal is humanitarian, "to aid Haiti's economic development through sustainable production activity," although he noted that it would also benefit Brazilian and US companies.
