Since Colombia's FARC guerillas called off their unilateral ceasefire following a military air-strike last month, peace talks with the government have resumed in Havana. As the new phase of talks opened May 25, FARC leaders appealed to the government to instate a bilateral ceasefire. (EFE, May 25) But the very next day, government forces carried out a mixed land and air assault on a camp of the FARC's 18th Front along the Río Chimirindó, in Riosucio municipality, in the Pacific coastal region of Chocó—leaving 41 guerillas dead. Among the dead was the 18th Front's commander, Román Ruiz, authorities said. (El Teimpo, May 26) The next day, Colombia's air force carried out new strikes, targeting the 4th Front of the FARC's Magdalena Medio Bloc at Alto la Cruz hamlet, Segovia municipality, Antioquia. Ten guerillas were killed in the strikes—which came as the climax of a three-day operation in the area that authorities said left 36 guerillas dead. (El Tiempo, May 27)

Colombia's Congress voted on June 3 to limit presidents to a single term, a measure backed by President Juan Manuel Santos. The presidential term limit undoes a law passed by Santos' predecessor and rival, Alvaro Uribe, and reverts to the term limits that were in place before 2005. Santos ran against his former mentor in 2010 and was re-elected last year but vowed to get rid of the constitutional reform passed under Uribe's leadership. The measure passed amid strong opposition from the Democratic Center party, led by Uribe. Surveys show that more than 70% of Colombians disfavor presidential re-elections due to abuse of power. Santos split from Uribe when Santos opened up talks with the Revolutionary Armed Forces of Colombia (FARC) in November 2012.

At least 18 FARC fighters were killed May 22 in an air-strike on a camp near the coastal village of Guapi in Colombia's southwest region of Cauca. The strike came little more than a month after President Juan Manuel Santos ended a suspension of aerial bombing in response to a guerilla attack that killed 11 soldiers. The army said the aim of the air-strike was intended to kill "Javier el Chugo," second-in-command of the FARC’s 29th front, although it wasn't immediately clear if he was among the dead. (Colombia Reports, May 22) The FARC responded to the bombardment by announcing its own suspension of a unilateral ceasefire the guerillas had declared in December. A statement from the FARC command said: "We did not seek the suspension of the unilateral and indefinite ceasefire proclaimed on Dec. 20, 2014 as a humanitarian gesture to de-escalate the conflict, but the incoherence of the Santos government has done it, through 5 months of ground and air offensives against our structures throughout the country."

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.

Colombia's President Juan Manuel Santos on May 9 called upon his National Drug Council to halt the spraying of glyphosate on suspected coca fields following its recent reclassification as a carcinogen by the World Health Organization. The decision to put an end to 20 years of the US-backed aerial spraying was applauded by leaders of the FARC guerillas. The spraying has long been opposed by the FARC as well as by Colombia's peasant communities. Santos' announcement came one week after government representatives and FARC leaders met in Havana for the 35th round of peace talks—this time to focus on justice and restitution for victims of Colombia's long civil war.

China's Premier Li Keqiang, on a tour of South America, is plugging a transcontinental railway project that would cut through the heart of the Amazon rainforest. Last year, President Xi Jinping signed a memorandum on the project with the governments of Brazil and Peru, and Li is now pressing for an actual feasibility study. According to an interactive map on Diálogo Chino website, the "Twin Ocean Railroad" or "Transcontinental Railroad" would start at Porto do Açu in Rio de Janeiro state, and cut through the Brazilian states of Goiás, Mato Grosso and Rondônia. It would terminate at Puerto Ilo in Peru's southern Moquegua region.

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.

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.
