Six men accused of murdering 13 crew members of two Chinese merchant ships on the Mekong River last year pleaded guilty Sept. 20 at their trial in Kunming, capital of China's Yunnan province. The defendants included Naw Kham (also rendered Nor Kham), purportedly one of the most powerful warlords in the Golden Triangle opium-growing region that straddles the borders of Burma, Thailand and Laos. The crew were massacred by an armed gang that attacked two cargo ships last October. Chinese media said the gang was involved in kidnapping as well as international drug running.

Arctic sea ice cover this month fell to the lowest summer minimum extent since satellite records began in 1979, according to the National Snow and Ice Data Center (NSIDC). "We are now in uncharted territory," said NSIDC director Mark Serreze. "While we've long known that as the planet warms up, changes would be seen first and be most pronounced in the Arctic, few of us were prepared for how rapidly the changes would actually occur."

As Mexico has aggressively militarized its "drug war" over the past years, the nation's capital has been an exception, with authorities reluctant to send soliders to patrol the seat of federal power—until now. Over 1,000 army troops have been mobilized to the streets of Nezahualcóyotl, a suburb of Mexico City, just south of the Federal District line in México state, which has seen a dramatic increase of violence in the past weeks. The México state Prosecutor General says 119 assassinations have been registered so far this year, mostly in Nezahualcóyotl. The decision to send in army troops—under a program dubbed "Operation Neza"—was apparently sparked by the Sept. 16 stabbing death of México state lawmaker Jaime Serrano Cedillo of the Institutional Revolutionary Party (PRI). Although subsequent reports have indicated he was killed by his wife in a domestic dispute, Serrano was the second PRI politician killed in as many days last week. On Sept. 15, Eduardo Castro Luque, newly elected to the Sonora state legislature, was shot full of nine bullets in front of his home in Ciudad Obregón. The twin slayings came when the country was on high alert for Independence Day celebrations, with extra troops deployed to conflicted states to head off terror attacks on the festivities. The PRI, a once-entrenched political machine, returns to power after 12 years in opposition, when president-elect Enrique Peña Nieto takes office in December.

Four protesters were killed in Benghazi Sept. 21 and over 20 wounded when citizens moved against militia groups in the eastern Libyan city, storming and occupying their bases. Hundreds of weapons were pilfered, and vehicles set ablaze. Among those seized was the headquarters of Ansar al-Sharia, the Islamist militia linked to the attack on the US mission in the city that killed the ambassador and three other US personnel. The stage was set for confrontation when Ansar al-Sharia called a rally of its own supporters in the city's central Shajara Square after the "Save Benghazi" rally—to oppose the lawless militias that continue to operate with impunity in the city—had been called for the same time and place. "Ansar al-Sharia have done this deliberately," said Bilal Bettamir, an organizer of the Save Benghazi rally. "We have been planning our march for the past week, and they made their decision yesterday. They knew all about it." But the jihadists apparently retreated as some 30,000 advanced on the plaza after Friday prayers, chanting "No, no, to militias," with banners reading "The ambassador was Libya's friend" and related slogans. After rallying in the square, groups of protesters started to overrun the militia bases. The four were killed while attempting to occupy the base of the Raf Allah al-Sahati Brigade, another Islamist militia.

Much of India was shut down Sept. 20 in a Bharat Bandh—an all-India general strike—called by opposition parties to protest new neoliberal economic measures by the center-left United Progressive Alliance (UPA) government. The bandh was most widely observed in Calcutta and Bangalore, which were virtually paralyzed. The Confederation of Indian Industry estimated losses of over $2 billion to the national economy. At issue was the UPA government's decision to hike fuel prices and allow foreign direct investment (FDI) in the retail sector—which the opposition charges will allow foreign-owend box-store chains to squeeze out local businesses. WalMart, reacting swiftly to the government announcement, has already announced plans to open outlets in India in the coming months. 

Japan's cabinet on Sept. 19 failed to approve recommendations of a special government-appointed panel to phase out nuclear power by 2040, in a move openly portrayed in the country's media as a capitulation to pro-nuclear businesses interests. The panel had called for a 40-year limit on the lifespan of nuclear power plants, no new plant construction, and no expansion of existing nuclear power facilities. The cabinet decision came on the same day that Japan launched a new body to oversee the industry, the Nuclear Regulation Authority, which replaces the existing Nuclear and Industrial Safety Agency. But critics say the new agency lacks any greater powers than the old one, and protest that its head, Shunichi Tanaka, who oversaw decontamination efforts at Fukushima, is a nuclear industry insider. 

Authorities from four countries cooperated in a months-long operation that led to the arrest Sept. 18 of Daniel Barrera AKA "El Loco"—dubbed the "last of the great capos" by Colombia's President Manuel Santos—on a street in San Cristóbal, a town in Venezuela's western Táchira state. Barrera was apprehended while making a call from a phone booth, allegedly after one of his relatives had given up his location. The arrest followed four months of cooperation between Colombia's National Police, the US Central Intelligence Agency (CIA), the UK's MI6 and Venezuela's National Anti-Drug Office (ONA). According to Colombia's defense minister, Juan Carlos Pinzón, the kingpin had been in Venezuela for the past eight months and was running his business while moving between several towns near the Colombian border.

At least 26 are dead, 50 injured and seven still missing after a Sept. 18 explosion at a Petróleos Mexicanos  (Pemex) gas pipeline distribution center on the outskirts of Reynosa, on the Texas border in Tamaulipas state. The dead include four Pemex employees and 22 private contractors. The pipeline serves wells in northern Mexico's Burgos basin, which have been repeatedly attacked for pilfering by criminal gangs such as Los Zetas. Last month, Pemex said the amount of petroleum products stolen in the first half of this year is up 18% compared to 2011, totalling more than 1.8 million barrels. But the company denied that criminal activity was linked to the Reynosa blast. (Brownsville Herald, Sept. 19; OilPrice, Aug. 21)
