Rebels in the Central African Republic Dec. 23 seized the key city of Bambari—the country's third largest—as part of their new offensive. The rebels—known as the Seleka coalition—have seized several towns north of the capital in recent weeks, charging that President Francois Bozize has failed to uphold a 2007 peace deal. The Libreville Comprehensive Peace Agreement, signed with former rebel groups, called for the release of prisoners and compensation to ex-combatants. The renewed insurgents also oppose plans by Bozize to alter the constitution to seek a third term, according to a statement signed by Seleka secretary general Justin Mambissi Matar.

The government of Puerto Rico and the US Justice Department signed a 106-page agreement on Dec. 21 for reforming the island's 17,000-member police department. The reforms are intended to address numerous police abuses detailed in a September 2011 Justice Department report; the American Civil Liberties Union (ACLU) issued its own report on abuses in June 2012. The Justice Department also filed a lawsuit requiring the Puerto Rican government and police department to comply with the Justice Department's earlier directives, but this was considered a legal formality, since the agreement apparently represents the compliance the US was seeking.

An Argentine federal court handed down life sentences on Dec. 19 to former Buenos Aires province interior minister Jaime Smart (1976-1979), former Buenos Aires province police investigations director Miguel Osvaldo Etchecolatz and 14 former police and military personnel for genocide and crimes against humanity in the cases of 280 people detained during the 1976-1983 "dirty war" against suspected leftists. Another seven police agents and civilians were given sentences of two to 25 years.

A wave of store lootings, the first in Argentina since 2001, started on Dec. 20 when people with covered faces broke into six supermarkets in San Carlos de Bariloche, in the southwestern province of Río Negro. At the request of local authorities, the center-left government of President Cristina Fernández de Kirchner sent 400 members of the Gendarmería militarized police to the city, which is best known as an Andean ski resort popular during the Southern Hemisphere's winter. The national government blamed small criminal gangs, while local authorities said anarchist groups were responsible.

Following up on an exposé last April of bribery by Wal-Mart de México, the Mexican subsidiary of US retailer Wal-Mart Stores, Inc., the Dec. 18 edition of the New York Times provided details on how the company used payoffs to get around community opposition and building and environmental regulations that might slow down its campaign to build more stores. Reporters David Barstow and Alejandra Xanic von Bertrab wrote that by reviewing tens of thousands of documents they had identified 19 Wal-Mart stores whose construction was aided by corruption.

The Mexican media have closely followed the renewed US interest in gun control after the killing of 20 children and eight adults in Newtown, Connecticut on Dec. 15. Laws regulating the sale of firearms in the US have an immediate impact on Mexico, where some 50,000 people have been killed since 2006 in the government's "war on drugs" and in fighting between rival drug cartels. Statistics that the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) submitted to the US Senate in 2011 indicate that some 70% of the illegal firearms seized in Mexico in 2009 and 2010 came from the US; Mexico itself has very strict controls on gun ownership.

Islamist militants occupying Timbuktu in northern Mali destroyed remaining mausoleums in the ancient city using pick-axes Dec. 23, a leader of the group said. "Not a single mausoleum will remain in Timbuktu, Allah doesn't like it," Abou Dardar, head of Ansar Dine, told the AFP. "We are in the process of smashing all the hidden mausoleums in the area." (Al Jazeera, Dec. 23) Three days earlier, the UN Security Council voted unanimously to approve an African-led intervention force to oust the Islamist forces from Mali's north.

The Egyptian opposition on Dec. 23 said it will appeal the referendum that appears to have voted in a new constitution backed by ruling Islamic parties. The opposition has alleged the vote was marred by fraud and irregularities, while the Muslim Brotherhood, the main supporters of the new constitution, claim the referendum has passed with 64% "yes" votes. Official results have not been released yet and are expected on Monday, Dec. 24. The National Salvation Front, the main opposition group, composed of united factions of liberals, socialists and others, had campaigned heavily for the rejection of the referendum.
