President Barack Obama formally notified Congress Oct. 14 that 90 US troops have been mobilized to Cameroon—the first contingent of a 300-strong force to assist in the struggle against Boko Haram. The force will conduct airborne intelligence, surveillance, and reconnaissance, but will not participate in ground combat operations (except in self-defense). Unarmed surveillance drones will also be deployed. The Pentagon said the move came at the invitation of Cameroon's government, which has been headed by strongman Paul Biya since 1982. Cameroon is part in a joint regional task force to fight Boko Haram along with Chad, Niger and Benin.

Okinawa's Gov. Takeshi Onaga on Oct. 13 revoked the approval issued by his predecessor for a landfill to relocate the US Marine Corps Air Station Futenma to a new site at the island's Cape Henoko. Sit-in protestors in front of Camp Schwab  Marine Base at Henoko rejoiced as the announcement came over a live radio broadcast. Some took over the roadway to perform the island's traditional Kachashi dance in jubilation. Hiroji Yamashiro, director of the Okinawa Peace Movement Center, voiced defiance of anticipated efforts by Japan's central government to override the decision: "We will not lose to the governments of Japan and the United States. With the governor, we will continue to struggle to stop construction of the new US base." In March, Gov. Onaga had issued a stop-work order on the relocation, which the central government overruled. Protesters are demanding that the US Marines leave Okinawa entirely. (Kyodo, Oct. 14; BBC News, Ryukyu Shimpo, Oct. 13)

On Sept. 26—one year anniversary of the disappearance of 43 students in Mexico's southern state of Guerrero—thousands of protesters filled the streets of Mexico City. The march, led by parents of the missing students, made its way from Los Pinos, the presidential residence, to the Zócalo, the capital's massive central square. Protests were also held in Iguala, Guerrero, where the 43 students from a teachers' college in nearby Ayotzinapa were abducted one year ago. Many carried mass-produced placards that read "Ni un desaparecido más, Ni un muerto más—¡¡Fuera Peña Nieto!!"—"Not one more disappearance, not one more death—Out with Peña Nieto!!" The administration of President Enrique Peña Nieto is under growing pressure in the case. There have now been 110 arrests of members of the Guerreros Unidos narco-gang, named by the government as responsible in the mass abduction. But there have been no convictions. The government says the students were massacred by the drug gang, and claims two sets of remains have been identified. But survivors, activists and rights observers say the official story doesn't hold water.

Indigenous leaders and activists interrupted an auction of oil and gas exploration blocs overseen by the Brazilian Agency of Oil and Gas in Rio de Janeiro Oct. 7, seizing the stage to discuss climate change, indigenous rights and divestment. The intervention by indigenous leaders in face-paint and traditional head-dresses was followed by a delegation of unionized oil workers who also spoke against the auction. The auction was described as a failure by local media, with only 37 of the 266 blocs sold. Many of fracking blocs extend deep into the Amazon rainforest, including the territories of remote and vulnerable indigenous peoples. The most critical blocs for isolated indigenous peoples are in the Juruá Valley and Serra do Divisor of Amazonas state, and the Javari Valley of Acre. Registered bidders included BP, Shell and ExxonMobil. (EcoWatch, Oct. 9; Brasil ao Minuto, Oct. 7; The Ecologist, Oct. 6)

At least five suicide bombers on Oct. 10 targeted a village in Chad that is home to thousands of Nigerians who have fled Boko Haram violence, killing at least 36 people and wounding about 50 others in co-ordinated attacks. Authorities blamed Boko Haram for staging the attacks in the village of Baga Sola, near the Nigerian border. Nearly half of the dead resulted when two female suicide bombers hit the village market when it was at its busiest. The following day, two female suicide bombers carried out the attacks in the Cameroon village of Kangaleri, again targeting a market district and killing nine. Both western Chad and northern Cameroon hosts thousands of Nigerian refugees. Another 1.5 million are internally displaced within Nigeria. (AFP, CBC, Sahara Reporters, Anadolu Agency)

Israel carried out an air-strike on the Gaza Strip Oct. 5 in response to a rocket attack from the territory—said to have been claimed by the "Sheikh Omar Hadid Brigade," a Salafist organization apparently affiliated with ISIS. Two rockets fired at Israel the previous night; one exploded in an open area in Eshkol, causing no injuries or damage, while the second failed to reach Israeli territory. The Omar Brigade—named after a figure who helped Abu Musab al-Zarqawi set up  al-Qaeda in Iraq a decade ago—has also claimed responsibility for rocket fire on the Israeli cities of Sderot and Beersheba last month. More air-strikes on Gaza were launched following a rocket launched Oct. 10, which was intercepted by Israel's Iron Dome defense system. The new air-strikes reportedly hit Hamas targets. (Haaretz, Oct. 11; Ma'an, Oct. 10; JP, AFP, Oct. 5) The ISIS franchise in Gaza had been previously named as the "Supporters of the Islamic State in Jerusalem."

The Tunisia Quartet civil activist group was awarded the Nobel Peace Prize on Oct. 9 for its pivotal role in channeling the country's revolution in a secular and democratic direction. The Quartet was formed in the summer of 2013, composed of four civil society groups—the General Union of Tunisian Workers (UGTT); the Tunisian League of Human Rights; the Bar Association; and the Tunisian Confederation of Industry, Trade and Handicrafts. It led what is called the National Dialogue, bringing together the country's fiercely adversarial political parties to forge a new democratic process. The groups opened the dialogue process amid an alarming political crisis, marked by political assassinations and turmoil. As other Arab countries were descending into civil war, Tunisia came back form the brink, adopting a secular constitution, thanks to a "vibrant civil society with demands for respect for basic human rights," in the words of the Nobel Prize Committee.

Damning evidence of war crimes by the Saudi-led coalition highlights the urgent need for independent, effective investigation of violations in Yemen and for the suspension of transfers of certain arms, said Amnesty International in a new report published Oct. 7. "'Bombs fall from the sky day and night': Civilians Under Fire in Northern Yemen" examines 13 deadly airstrikes by the coalition in Sa'da, northeastern Yemen, which killed some 100 civilians, including 59 children. The report documents the use of internationally banned cluster bombs. "This report uncovers yet more evidence of unlawful air-strikes carried out by the Saudi Arabia-led coalition, some of which amount to war crimes. It demonstrates in harrowing detail how crucial it is to stop arms being used to commit serious violations of this kind," said Donatella Rovera, Amnesty's senior crisis response adviser who headed the organization's fact-finding mission to Yemen. "The USA and other states exporting weapons to any of the parties to the Yemen conflict have a responsibility to ensure that the arms transfers they authorize are not facilitating serious violations of international humanitarian law."
