Chinese authorities carried out aggressive detentions ahead of the 25th anniversary  of the Tiananmen Sqauare massacre, with New Tang Dynasty news agency reporting 70 journalists, dissidents and rights defenders arrested over the past month. Blogger and journalist Gao Yu went missing at the end of April, and Beijing activist Hu Jia has been under house arrest for more than three months, after announcing his intention to hold a vigil in the square on the June 4 anniversary, in defiance of authorities. The Wall Street Journal's China Real Time blog notes that tens of thousands attended a vigil in Hong Kong, but the New York Times' Sinosphere blog reports that Tiananmen Square itself was so thick with security patrols and checkpoints that even the usual throng of tourists was down to a mere trickle. A tantalyzing report in the Globe & Mail says that a small group of black-clad citizens did manage to walk through the square in a silent, symbolic protest.

For the first time, the US Environmental Protection Agency has proposed to limit emissions of the greenhouse gas carbon dioxide from existing power plants, the single largest source of carbon pollution in the United States. The response has been predictable. Environment News Service notes: "Democrats and public health and environmental groups rejoiced in the proposal of a measure they have advocated for years to fight climate change, but Republicans cried doom, warning that the rule would destroy the American economy." The New York Times writes: "[E]nvironmental advocates praised the proposed rule for its breadth and reach while the coal industry attacked it as a symbol of executive overreach that could wreak economic havoc." The Daily Beast's Jason Mark dubbed the program "Obamacare for the Air" because both plans are "numbingly complex," "based on a market system," "likely to transform a key sector of the economy," and "guaranteed to be intensely polarizing." In other words, a market-based plan is being attacked by the right as green totalitarianism. This would be perverse enough if the plan's goals were anywhere close to sufficient to actually address the climate crisis—which, again predictably, they are not.

Colombia's government and the FARC guerilla organization announced an agreement May 16, entitled "Solution to the Problem of Illicit Drugs," in which they pledge to work together against the narco trade. The FARC, whose top leaders face extradition to the United States on trafficking charges, agreed to "end any relationship" with the illicit drug trade, and cooperate in a "National Program for the substitution of the illicit uses of coca, poppy, and marijuana crops." The accord calls for "integral development plans" for rural communities impacted by the drug trade, to be drawn up with the participation of those communities, in the context of an "Integral Rural Reform." It also calls for an international conference to be held under the auspices of the UN to reconsider global strategies against drugs—the one veiled reference in the agreement to the FARC's earlier proposals to decriminalize cultivation of coca leaf and cannabis. "With this we will eliminate the gasoline that has fuelled the conflict in Colombia—drug trafficking," said the government's lead negotiator, Humberto de la Calle.

Now comes the disturbing news that a Frenchman arrested in the killings at the Brussels Jewish museum had traveled to Syria as an insurgent and is apparently linked to the Islamic State of Iraq and Syria (ISIS). Police in Marseille arrested the suspect, Mehdi Nemmouche, after he arrived on a bus from Amsterdam May 30. Paris Prosecutor Francois Molins said he had an automatic weapon like that used in the Brussels attack, and ballistics analysis is underway to determine if it is the same weapon. The rifle was reportedly wrapped up in a white sheet scrawled with the name of ISIS. Police in Belgium meanwhile say the suspect had tried to film the May 24 killings, but his camera failed. Belgian federal prosecutor Frederic Van Leeuw said: "The new elements in this investigation draw attention once more to the problem of the 'returnees'—in other words the people going to Syria to participate in combat and return afterward to our country. All European countries are confronted at this moment with this problem." (AP, June 1) The days since the arrest have seen more raids on suspected "returnees" in France. Four were arrested in the Paris area and southern France on suspicion of recruiting militants to fight in Syria. Interior Minister Bernard Cazaneuve told Europe 1 radio: "There are people who recruit jihadists... We are acting everywhere. There will be no respite in the fight against terrorists."

Three independent UN human rights experts on June 2 urged Pakistan to adopt urgent legislation to put an end to faith-based killings and protect the country's Ahmadiyya Muslim (BBC profile) community, whose faith is currently outlawed. The call follows a resurgence of violent attacks in Pakistan targeting Ahmadiyya Muslims, which have resulted in the deaths of two members of the community and are believed to be related to the practice of their religious faith. The country has also recently seen many arrests for blasphemy. Special Rapporteur on freedom of religion or belief Heiner Bielefeldt said that the violence was "fueled by existing blasphemy legislation in Pakistan particularly targeting minorities." He went on to urge the country to guarantee the right to freedom of religion or belief for members of minority religious communities. Special Rapporteur on extrajudicial, summary or arbitrary executions  Christof Heyns also spoke, stressing the importance of ensuring accountability to the government's efforts to reduce attacks. Pakistan, according to Heyns, must take urgent and firm steps to bring justice to those guilty of such killings.

Sixty hunger striking Palestinians in Israel's Eshel prison are being held in solitary confinement, a prisoner rights group said June 3. The Palestinian Prisoners' Society said in a statement that the number of prisoners hunger striking in the Beersheba prison of Eshel had reached 60 and that each of the strikers was being held in solitary confinement. A spokesman for the Israeli Prison Service did not immediately return calls seeking comment. The prisoners are among hundreds refusing meals in solidarity with administrative detainees who have been on hunger strike for 41 days. 

Iranian women by the thousands are posting their photos without a hijab on a Facebook page called My Stealthy Freedom, created by London-based Iranian journalist Masih Alinejad, and winning over 180,000 "likes" since it was launched May 3. Women post photos of themselves in varying degrees of defiance, from some only showing the backs of their heads while others standing bareface in front of government offices. "It is painful that I shall not be free so that you will not sin," comments one woman below her photo. "That I have to be covered so that your weak faith does not break!" The women, generally anonymous, are standing up against the Islamic Republic's 35-year law that requires women to dress according to sharia law. In addition to the head covering, they cannot wear clothing that exposes their arms or legs, and must wear a cloak or overcoat that covers three-quarters of the body. The semi-official Fars News Agency has condemned the page and accused Alinejad of inciting immoral behavior and collaborating with Iran's enemies. (Mid East Faces, May 14)

US President Barack Obama announced May 31 that prisoner of war Bowe Bergdahl had been released into US custody in exchange for five detainees held at Guantánamo Bay. Bergdahl was the only confirmed US prisoner of war from the conflict in Afghanistan remaining in enemy custody. The Obama administration brokered the deal for Bergdahl's exchange through the Qatari government; once Bergdahl was secured, five high-profile Guantánamo Bay detainees, including the former head of the Taliban army, were transferred to Qatar. Republicans in the US Senate and House of Representatives criticized the exchange, which had been conducted in violation of a law requiring the president to notify Congress 30 days before any detainees are transferred from Guantanamo bay (PDF). The Obama administration maintains that the provision of the law requiring the notification is an unconstitutional violation on his rights as Commander-in-Chief (signing statement, PDF).
