Just weeks after the Mexican government signed an accord with the "community police" vigilante network in Michoacán, ostensibly bringing the anti-narco militias under control of the armed forces, it is looking more and more like they have been transformed into a lawless paramilitary force—even acting against Mexico''s federal authorities. On March 19, "community police" forces at La Placita, on Michoacán's Pacific coast, launched a blockade of the entrance of a Mexican naval outpost, apparently in protest of the disarming of 14 of their gunmen by Mexican marines stationed there. The blockade escalated in the following days, with hundreds of armed vigilantes from neighboring towns converging at the base. (El Sol de Leon, March 21)

On April 1, the 50th anniversary of the military coup that removed left-leaning Brazilian president João Goulart (1961-64) from office, the Washington, DC-based research group National Security Archive posted 16 Brazil-related documents from the administration of US president John Kennedy (1961-1963) on its website. The documents—which include declassified National Security Council (NSC) records and recently transcribed tapes of White House conversations—detail the administration's efforts to bring President Goulart into line, and its plans for dealing with him if he continued to implement social reforms and to oppose US policy on Cuba.

The US Agency for International Development (USAID), a US government foreign aid agency, secretly ran a cell phone-based imitation of the Twitter social networking service in Cuba from 2010 to 2012, according to an April 3 report by the Associated Press (AP) wire service. The service—named "ZunZuneo," Cuban slang for a hummingbird's tweet—was developed in conjunction with two private contractors, the Washington, DC-based Creative Associates International and the Denver-based Mobile Accord. ZunZuneo was popular with young Cubans, who were unaware of its origin; by 2012 the service had some 40,000 subscribers.

Four people died the morning of April 5 in a confrontation between indigenous Mexicans over land in Chilón municipality in the highland region of the southeastern state of Chiapas. The violence broke out when some 25 people tried to remove members of the Regional Organization of Autonomous Ocosingo Coffee Growers (ORCAO) from a 84-hectare ranch; sources differ on whether the ranch is called San Luis or Luis Irineo. The attackers were apparently egged on by the former owner of the ranch, which a group of ORCAO members took over in 1994. On April 6 the state attorney general's office announced that four people had been arrested in the incident. (La Jornada, Mexico, April 6; SDP Noticias, Mexico, April 6)

On March 25 a Tegucigalpa court convicted three men in the May 2012 murder of Honduran journalist Angel Alfredo Villatoro Rivera. Marvin Alonso Gómez and the brothers Osman Fernando and Edgar Francisco Osorio Argujo are scheduled to be sentenced on April 25; prison terms could range from 40 years to life. At least 40 Honduran journalists have been murdered in the past decade, with few convictions. Cases include the July 2013 kidnapping and murder of television journalist Aníbal Barrow and the October 2013 shooting death of Globo TV camera operator Manuel Murillo Varela. The French-based organization Reporters Without Borders (RSF) ranks Honduras 129th out of 180 countries in its 2014 press freedom index. (Thomas Reuters Foundation, March 28; IFEX, March 31)

Pro-Russian protests broke out in Ukraine's east April 6, climaxing in the seizure of government buildings in the cities of Donetsk, Kharkiv and Luhansk. (See map.) Protesters in Donetsk declared their own "constituent assembly," and proclaimed the Donbas region to be a "people's republic." After clashing with riot police and breaking through their lines to enter the regional parliament chamber, the protesters raised the Russian flag from the building. Supporters outside cheered and chanted: "Russia, Russia!" A report by Russia's Interfax agency said the Donetsk protesters will push for a regional referendum by May 11 on unification with Russia. Protest camps have been established outside the government buildings in all three cities, with banners bearing messages such as "Putin, help!"

NATO on April 1 began a two-day exercise, briging more than 100 US Air Force personnel, along with F-15 fighter jets and a Germany-based Airborne Warning and Control System (AWACS) craft, to former Soviet air bases in Lithuania. Denmark is also sending six F16 fighter jets to the Baltic as part of an expanded NATO air policing mission, with regular patrols to begin May 1. The incidence of Russian jets flying close enough to Baltic airspace this year to prompt NATO jets being scrambled has increased to about once a week, according to Lithuania's defense ministry. NATO jets were scrambled about 40 times in both 2012 and 2013; in 2004, the year the Baltic republics joined NATO, it only happened once.

A judge for the US District Court for the District of Columbia dismissed a lawsuit (PDF) on April 4 brought against officials of the Obama administration for the 2011 drone strikes that killed three US citizens in Yemen. The lawsuit was specifically brought against former defense secretary Leon Panetta, former CIA director David Petraeus and two commanders in Special Operations forces. Judge Rosemary Colleyer found that there were serious constitutional issues in the case but that "this case would impermissibly draw the court into 'the heart of executive and military planning and deliberation.'" Three US-born alleged al-Qaeda leaders and propagandists, Anwar al-Awlaki, his son Abdulrahman al-Awlaki, and Samir Khan, were killed by the drone strikes in 2011. The elder al-Awlaki has been linked to several attacks on the US, including an attempt on Christmas Day 2009 on a Detroit-bound airplane.
