Peru's authorities can't seem to put out the last flicker of the Sendero Luminoso insurgency. A generation ago, the Maoist guerillas seemed capable of toppling the government but are now largely confined to a remote pocket of jungle known as the Apurímac-Ene-Mantaro River Valley (VRAEM). But that happens to be a top coca cultivation zone, affording the insurgency access to funds. Now, authorities claim to have uncovered evidence that the neo-Senderistas are in league with one of the re-organized Colombian cocaine cartels, ironically known as the "Cafeteros" (coffee-producers). "For the first time in an objective and concrete manner, the state can corroborate the link between drug trafficking and terrorism in the VRAEM," Ayacucho regional anti-drug prosecutor Mery Zuzunaga told Cuarto Poder TV.

Thousands of Guatemalans took to the streets May 16, demanding the nation's President Otto Pérez Molina step down amid a scandal that has already forced the resignation of his vice president, Roxana Baldetti. Despite rain, protesters marched in 13 cities. Throngs filled the capital's central plaza, where a giant banner read "We are the people." The mobilization was largely leaderless, organized by social media under the hashtag #RenunciaYa (Resign Already). It all blew up in April, when the UN International Commission Against Impunity in Guatemala released findings of an investigation into a customs bribery ring uncovered by Guatemalan prosecutors. Baldetti's private secretary, Juan Carlos Monzón, was named as the ringleader, forcing Baldetti to step down May 8—despite protesting her innocence. Pérez Molina likewise pleads ignorance about the ring, dubbed "La Línea," and pledges a crackdown on corruption. Monzón is on the lam and an Interpol warrant has been issued.

Mexico's drug cartels appear to have declared open season on any candidate for public office who will not toe their line in the run-up to June's midterm elections. On May 14, mayoral candidate Enrique Hernández Salcedo was shot to death by gunmen who fired from a passing truck as he was making a speech in the town of Yurécuaro, Michoacán. Three spectators were injured. Hernández was a leader of the town's "self-defense force," which took up arms to break the grip of the Knights Templar drug cartel in the region. He was running with the left-opposition Morena party.

Maya indigenous peasants in Mexico's southern state of Chiapas are marching cross-country to oppose violence by the local narco gangs and the corruption of local authorities that protect them. The "pilgrimage" left the rural town of Simojovel some 15,000 strong at the end of March, and is now arriving at the state capital Tuxtla Gutiérrez, some 240 kilometers away through rugged country. The pilgrimage was organized by the Catholic pacifist group Pueblo Creyente (Faithful People) with the support of the local diocese of San Cristóbal de Las Casas in response to a wave of narco-violence in Simojovel.

March 28 saw more angry protests in Mexico's conflicted southern state of Guerrero, as students from the rural college of Ayotzinapa clashed with police in the state capital Chilpancingo at a march demanding the return alive of the 43 abducted students from the school. Cars were set on fire as police attacked the marchers. The 43 students disappeared during protests in the Guerrero town of Iguala last September, and are now believed to have been turned over a murderous narco-gang by corrupt police. The weekend before the Chilpancingo demonstration, family members of some of the 43 missing students held a vigil in New York City's Union Square—one stop on a tour of US cities to raise awareness on their plight and protest Washington's "Drug War" aid to Mexico's brutal and corrupt police forces.

DEA agents in Colombia held sex parties with prostitutes hired by narco-traffickers, according to an investigation by the US Justice Department released March 26. In a series of interviews with DoJ's Office of the Inspector General, former Colombian police officers said that they arranged the parties at government-leased quarters between 2005 and 2008, and also provided protection for the agents' weapons and property during the affairs. The report goes on to detail how several DEA agents were provided money, gifts, and weapons by local drug cartel operatives.

The dizzyingly escalating crisis across the Middle East was ratcheted up several degrees last week as Saudi Arabia and its Gulf State allies intervened in Yemen, launching air-strikes against the Shi'ite rebels that have seized much of the country. Saudi troops are amassing on the border and there are fears that the air campaign, dubbed "Operation Decisive Storm," may soon be followed by a ground invasion. Within Yemen, Sunni tribes and militants in al-Qaeda's orbit are also battling the Shi'ite rebels, known as Houthis. (CNN, Al Jazeera, March 29; Yemen Post, March 22)

Authorities in Colombia are carrying out their biggest manhunt since the campaign that brought down the legendary Pablo Escobar in 1993. Dario Antonio Usuga AKA "Otoniel" is leader of the Urabeños, a blood-drenched paramilitary network which is said to control much of the cocaine trade in Colombia's northern region of Urabá. The hunt, dubbed the "Siege of Urabá," has mobilized over 2,000 soldiers and National Police troops to the jungles and peasant villages of the northern region. Under a new reward just announced by President Juan Manuel Santos, Otoniel now has a $580,000 price on his head, while his associates "El Galivan," "Nicolas" and "Guagua" each have a price of nearly $200,000.
