A Japanese appeals court is expected to rule soon in a suit filed on behalf of 14 children by their parents and anti-nuclear activists in June 2011 in a district court in Fukushima arguing that the nearby town of Koriyama should evacuate its children to an area where radiation levels are no higher than natural background levels in the rest of Japan, or about 1 millisievert annual exposure. After the Fukushima accident, Japan set an annual exposure limit of 20 millisieverts for determining whether people can live in an area. The average radiation for Koriyama is below this level, but some "hot spots" around the city are above the cutoff. The district court rejected the suit in a December 2011 decision. An appeal is now before the Sendai High Court in nearby Miyagi prefecture.

Some 400 campesino protesters at the site of the Conga mining project in Peru's Cajamarca region on April 11 stormed the 200-strong lines of the National Police Special Forces Division (DINOES), to occupy the area around  El Perol lake, where they vandalized property, putting pipes and other equipment to the torch. The Yanacocha mining company evacuated its personnel and removed its machinery from the site. About 150 protesters continued to occupy the property, although Yanacocha said the next day that they had all been evicted. Comuneros from the provinces of Celendín and Bambamarca led the action, pressing demands that Yanacocha halt all operations at the site.

Ecuador's second-largest oil pipeline burst on April 8, but exports will not be affected, the Energy Ministry emphasized. The 475-kilometer Heavy Crude Oil Pipeline has a capacity of up to 450,000 barrels per day, linking oil fields in the eastern Sucumbios province to the Pacific coast. The Energy Ministry said that around 5,500 barrels of crude were spilled when the OCP broke, and that the pipeline suspended operations following the incident. The rupture occurred in Esmeraldas province, near where the pipeline meets the Pacific. Several local campesino plots were fouled. The OCP is controlled by a consortium including Spain's Repsol-YPF, the French Perenco and Brazil's Petrobras. The country's largest pipeline, the SOTE, transports crude for paratstatal Petroamazonas, which aims to produce an average 325,000 bpd this year. (Reuters, El Comercio, Quito, April 8) Ecuador has just announced plans for a major new thrust of oil development in the Amazon, with Chinese companies in the lead.

The Brazilian state of Acre declared a state of "social emergency" April 10 in response to a surge of undocumented migrants from neighboring Bolivia and Peru—originating in countries from Haiti and the Dominican Republic to Bangladesh to Senegal and Nigeria. Officials said some 1,700 migrants had arrived during the past two weeks. The state "has been turned into an international travel route controlled by coyotes,"  said Nilson Moura, Acre's secretary for Justice and Human Rights., referring to the smugglers who guide the migrants into Brazil, often in exchange for exorbitant fees. The jungle town of Brasileia has become a key transport point for migrants bound for Sao Paulo and Rio de Janeiro. Brazilian police last year raided a number of sweatshops in Sao Paulo and the capital, Brasilia, where undocumented immigrants from Bolivia and Pakistan were found working in unsafe conditions for very little or no pay.

UN Special Rapporteur on human rights and counter-terrorism Ben Emmerson on April 12 called on the international community to protect Burkina Faso from terrorism, warning that attacks on the country's infrastructure or security would undermine social cohesion within the country, impair inward investment and further destabilize the region. Burkina Faso is particularly vulnerable due to its geographical proximity to the conflict in Mali, with which it shares a border. Emmerson described the country's role in regional peace negotiations:

A Pakistan court on April 5 extended by six days the bail granted to former president Pervez Musharraf, who faces charges of detaining judges during his time in office. The Islamabad High Court also ordered Musharraf to post bond for Rs 500,000, or just over $5,000, and to appear for his next hearing scheduled for April 18. Musharraf has also been named as a suspect in the assassination of former prime minister Benazir Bhutto in 2007, and may face charges in connection with the murder of Baluch tribal leader Nawab Akbar Bugti in 2007.

It was one year ago that Tuareg rebels of the National Movement for the Liberation of Azawad (MNLA) seized control of the vast desert north of Mali, and declared an independent state in the remote territory which had long been a sort of internal colony. But within weeks, control of Azawad was usurped by jihadist factions, who drove the MNLA from the territory. After months of harsh sharia rule in northern Mali, France intervened late last year, helped government forces drive back the jihadists, and established tenuous control over the north. Sporadic fighting continues, and the MNLA have joined the offensive against the Islamists, while stressing their independence from the French and government forces. The MNLA now have control of the town of Kidal, in an uneasy alliance with French-backed Chadian troops. But French Foreign Minister Laurent Fabius, visting the capital Bamako last week, said the MNLA will have to accept being disarmed and "confined." An AP report of April 7 noted celebrations by Tuaregs on the anniversary of the MNLA's takeover, but also implied that the rebel group has abandoned its separatist aspirations. Moussa ag-Assaride, the MNLA's communications chief, was cited as saying he knew that many in northern Mali are not aware that the group officially is no longer seeking independence. "But that doesn't stop the population from showing their joy," he said. 

At least 15 were killed April 10 in a series of confrontations in Mexico's increasingly conflicted Michoacán state. The first confrontation began when federal police aboard a helicopter spotted armed men traveling in four vehicles at Charapando in the muncipality of Gabriel Zamora. The gunmen opened fire on the agents, who shot back and killed five, a police statement said, adding that one of those killed was high in the leadership structure of a local drug cartel, which was not named. Two police agents were reported wounded. Hours later in the town of Apatzingan, federal agents were accompanying a procession commemorating the anniversary of the death of Mexican revolutionary Emiliano Zapata when gunmen opened fire with AK-47s. Police returned fire, killing one. Another eight were killed elsewhere in Apatzingán, when gunmen attacked a police checkpoint where trucks full of harvested lime were backed up; two police were injured, but the dead were all civilians. Schools in Apatzingán and Buenavista Tomatlán municipalities have been closed due to the violence.
