Nigerian militant network Boko Haram has claimed responsibility for the April 14 bombing of a bus station in Nyanya, a suburb of the capital Abuja, that killed 75 people. In a video message, Boko Haram commander Abubakar Shekau says he ordered the attack, but says nothing about the mass abduction of more than 100 teenage girls from a secondary school in Chibok, Borno State, most of whom are still missing. In the video, Shekau describes the bombing as a "tiny incident," and warns of many more to come. In words directed by name at President Goodluck Jonathan, Shekau says: "Jonathan, you are now too small for us. We can only deal with your grand masters like Obama the president of America. Even they cannot do anything to us. We are more than them."

Brazilian Military Police backed by Marine troops occupied the massive Maré favela next to Rio de Janeiro's Galeao international airport on March 31, allegedly without firing a shot. The aim was to secure one of the city's most violent districts, long under control of drug gangs, ahead of the World Cup, to be held in Brazil in June. Shock troops of the elite Special Police Operations Battalion (BOPE) and Marines in armored vehicles and helicopters secured the Maré area, where 130,000 people live in poverty on the north side of Rio. Police said they seized guns and 450 kilos of marijuana, and arrested two suspected dealers. But residents said most gang leaders slipped out the favela ahead of the occupation. The operation had been expected; in preceding days Police Pacification Units (UPPs) had been installed in 174 of Rio's favelas— home to around 600,000 people.

The offices of the Cali Municipal Workers Synidicate (Sintraemcali), located in the center of the Colombian industrial city, was attacked with hurled incendiary bombs April 16, causing damage to the facade and plumbing of the building. Sintraemcali called the bombing a "terrorist attack," and pledged to file a complaint with the Inter-American Human Rights Commission. The attack came five days after a judge in Bogotá ordered the president of the republic, Juan Manuel Santos, to issue a formal pardon to members of Sintraemcali, the Colombian University Workers Syndicate (Sintraunicol) and the Bogotá Telecommunications Workers Synidate (Sintratelefonos), who had been accused by former president Álvaro Uribe Vélez of being linked to terrorist groups and constituting a "Brotherhood of Terrorism."

Algerian security forces on April 16 violently dispersed an attempt by opposition activists to stage a protest in the capital against President Abdelaziz Bouteflika's run for a fourth term in this week's elections. Only a few members of the opposition alliance Barakat—President Abdelaziz Bouteflika—were able to assemble in central Algiers before police routed them. Barakat was able to hold a rally in a stadium, where some 5,000 gathered to chant "Boycott" and "The people want the regime out!" Mohsen Belabes, a leader of the Rally for Culture and Democracy (RCD), told the crowd: "The people here are the people who have been excluded, who have been put aside, but this is the real Algeria. The regime will collapse, but Algeria will survive."

The United States and Turkey have said they are following up on renewed accusations that the Syrian regime continues to use chemical weapons against civilians. If true, the government's use of such weapons would be a violation of its agreement with the Organization for the Prohibition of Chemical Weapons, and the Chemical Weapons Convention, both of which it signed last September. Over the past few months, members of the Syrian opposition, including the main umbrella group the Syrian National Coalition, have accused the regime of using chemical weapons, mainly in the suburbs of Damascus, in areas such as Jobar and Harasta. "There have been at least four such attacks in recent months, involving high doses of chlorine and pesticides," said Sinan Hatehet, director of the Coalition's media office. He added that although the attacks only killed around 15 people, the chemicals were primarily being used as a psychological weapon.

An official from the capital district government of Bogotá on March 28 called upon Colombia’s national government to open debate on broadening the policy of cannabis decriminalization. "We really need leadership from the Congress and the government to regulate the medicinal and recreational use of marijuana," said secretary general of the Bogotá mayor's office, Susana Muhamad. Despite efforts by the previous president Alvaro Uribe to roll back the policy, since 1994 cannabis has been decriminalized in small quantitites—recently established by the judiciary as up to 22 grams. However, sale and cultivation remain illegal. Muhamad appealed to current President Manuel Santos to examine lifting these limitations.

Coca-growers in Bolivia's lowland jungle town of Yapacaní on March 27 clashed with police in a protest against the construction of a new base of the Mobile Rural Patrol Unit (UMOPAR), the hated coca-eradication force. Protesters set up roadblocks in an effort to prevent construction crews from breaking ground on the new base. When National Police troops used tear-gas to break up the blockades, protesters replied by hurling rocks. Regional police commander Johnny Requena blamed drug gangs for the opposition to the base, which is being financed by the European Union to the tune of $1.3 million.

Brazilian police have closed down a notorious security firm accused of killing at least two Guarani leaders, and brutally attacking hundreds more. Gaspem was described as a ‘private militia’ by public prosecutors who had called for the closure last year. Ranchers reportedly paid Gaspem 30,000 reais (US$ 13,400) each time it evicted Guarani Indians from their lands, which are now occupied by sugar cane and soya plantations, and cattle ranches. The company's owner, Aurelino Arce, was arrested in 2012 in connection with the murder of Guarani leader Nísio Gomes. For years, the Guarani have been appealing for the company to be shut down. A judge's decision to force the company to close marks a huge victory for Guarani communities across the central state of Mato Grosso do Sul.
