Mali's prime minister Cheick Modibo Diarra was forced to resign on state television Dec. 11 after junta troops arrested him for attempting to leave the country. President Dioncounda Traoré appeared on TV to appoint Django Cissoko, a French-educated university professor and presidential aide, as interim prime minister. Diarra's ouster was a show of force by a military that staged a coup in March, just as rebels were seizing the country's desert north. Following his arrest, Diarra was taken to a meeting with coup leader Capt. Amadou Sanogo, where he was accused both of failing to retake the north and of scheming to to disrupt talks now underway with the rebels.

Juventina Villa Mojica, an environmental activist in the village of Coyuca de Catalán, in Mexico's southern state of Guerrero, was murdered along with her 10-year-old son on Nov. 28, in a mountaintop attack by up to 30 gunmen. Villa had ridden in an all-terrain vehicle with her two children up a mountain to get a cellphone signal, as there are no telephones in the village.  Her seven-year-old daughter survived unharmed. State prosecutors report that the ambush took place despite the presence of 10 state police officers who had been assigned to protect her following death threats on Villa and deadly attacks on her family members. Manuel Olivares Hernández, director of the local Centro Morelos human rights group said Villa was targeted by narco gangs for her efforts to protect the forest. "It's a virgin area with rich forest areas, and the main interest of drug traffickers is cutting down the trees so that once it is deforested they can expand their drug fields," Olivares said.

A total of 19 bodies have been found in clandestine graves in northern Mexico's Chihuahua state, officials from the state prosecutor's office said Nov. 26. The first 11 were discovered in what was described as a deserted area of La Colorada ranch, in the community of Ejido Jesús Carranza, 40 kilometers southeast of Ciudad Juárez near the Texas border. The bodies were said to be two years old. The victims were asphyxiated, shot or beaten, their ages ranged from 18 to 40 years old, and they included US citizens. Information leading to the discovery came from the US consulate in Ciudad Juárez, Chihuahua authorities said. That same day, eight more bodies were unearthed near Rosales, in Chihuahua's interior. These bodies were just two days old, and bore signs of torture. Some had been burned, beaten and had eyes carved out before being shot in the head. Four more bodies were found along the highway near the mountain outpost of Creel.

Complaints about abuses by Mexican police and soldiers have increased dramatically over the past seven years, according to testimony by Raúl Plascencia Villanueva, the president of the government's National Human Rights Commission (CNDH), to the Mexican Senate's Human Rights Commission on Nov. 21. Plascencia was reporting principally on the period from Jan. 1, 2005 to July 31, 2012, which overlaps the administration of President Felipe Calderón Hinojosa and his militarization of the "war on drugs." Calderón took office on Dec. 1, 2006; he will be succeeded this Dec. 1 by Enrique Peña Nieto.

A study released late last month by the Mexican Institute for Competitiveness, an elite think-tank based in Mexico City, asserted that proposals to legalize cannabis in Colorado, Washington and Oregon could cut Mexican drug cartels' earnings from traffic to the US by as much as 30%. The study, entitled "If Our Neighbors Legalize," drawing on previous research by the RAND Corporation, predicts that legalization in any US state would help drive down the price of high-quality domestic cannabis, undercutting the cheaper and less potent cartel imports. It calculated a loss of $1.425 billion to the cartels if Colorado legalized, $1.372 billion if Washington legalized, and $1.839 billion if Oregon voted yes. (AP, Nov. 1) In the Nov. 6 vote, initiatives calling for legalization of cannabis under regimes of state control were approved by voters in Colorado and Washington, but rejected in Oregon.

Brazilian police this month launched "Operation Saturation" to crush the Sao Paolo criminal network known as the First Capital Command (PCC), in response to the mafia's campaign of assassinations of police officers and employees. So far this year, 95 officers have been murdered in and around the sprawling city, according to official figures—up from 47 in 2011. Most were ambushed off duty by presumed gang members. Operation Saturation was launched after Marta Umbelina, an office worker at Sao Paolo's military police, was shot dead in front of her house and in sight of her 11-year-old daughter Nov. 3. In one of the operation's raids, military police found what they say is a hit list with the names and addresses of 40 officers.

The US Treasury Department sanctioned a senior Taliban official on Nov. 15 for his alleged role in the Afghan opium trade, saying the traffic is used to finance insurgent activities. Mullah Naim Barich, who operates as Taliban "shadow governor" in Helmand province, is named in the action, which freezes any of Barich's assets held under US jurisdiction and bars anyone in the United States from conducting any financial or commercial transactions with him. "Today's action exposes the direct involvement of senior Taliban leadership in the production, manufacturing, and trafficking of narcotics in Afghanistan and underlines the Taliban's reliance on the drug trade to finance their acts of terror and violence," David Cohen, Treasury under-secretary for terrorism and financial intelligence, said in a statement.

After more than two months of investigation, on Nov. 9 Mexico's federal Attorney General's Office (PGR) confirmed that it was formally charging 14 federal police agents for an Aug. 24 attack on a US embassy van on a road near the Tres Marías community, south of Mexico City in the state of Morelos. The agents claimed they mistook the van's occupants—two agents of the US Central Intelligence Agency (CIA) and a Mexican marine—for members of a gang connected to a local kidnapping. The two CIA agents were wounded in the incident.
