The death toll of US soldiers in Iraq passed 4,000 March 23 as four troops died in a roadside bomb attack on a patrol in southern Baghdad. More than 29,000 US soldiers have been wounded in five years of conflict in Iraq, according to the icasualties.org website. At least 97% of the deaths have come after George Bush announced the end of "major combat" in Iraq on May 1, 2003. At least 50 Iraqis, most of them civilians, also died March 23 in violence including bomb blasts and shootings.

At least 52 are dead following a March 17 bomb blast near the shrine of Imam Hussein, a pilgrimage center for Shi'ites in Karbala. Most reports identified a female suicide bomber as the perpetrator, but the Karbala police chief said it had been a bomb planted in a crowded area. About 75 were injured in the blast, the worst attack on Shi'ite civilians since the Ashura holy period.

Colombia has asked Mexico to investigate ties between Mexican citizens and the FARC guerrillas after four Mexicans were found among the dead in Colombia's March 1 strike on a rebel camp in Ecuador. In disclosing the request, Mexico's Exterior Secretariat said the government had opened a probe into whether the country harbors FARC collaborators. "The Mexican government is worried that Mexican citizens might be involved with an organization like the FARC," the secretariat said in a statement.

Following litigation against Chiquita Brands International for its payments to Colombia's right-wing paramilitaries, the families of five missionaries and lay workers with the Florida-based New Tribes Mission killed by the FARC guerillas in 1994-5 have filed suit against the company in federal court in Miami. The 63-page complaint claims Chiquita provided "numerous and substantial hidden payments" to the rebels in addition to weapons and supplies, amounting to support for "acts of terrorism."

As the Bush administration heads into months of negotiations with Prime Minister Nouri al-Maliki on the future of US troops in Iraq, it aims to stretch the bounds of executive power to unprecedented lengths. The administration plans to bypass Congress to forge a status of forces agreement (SOFA) that would grant the US an unlimited "authority to fight" provision, according to statements by the State Department's Coordinator for Iraq, David Satterfield, and Assistant Secretary of Defense Mary Beth Long, at a House Foreign Affairs Committee hearing last week. Drafts of the SOFA, a binding pact, also provide legal immunity for US private contractors operating in Iraq, according to a January New York Times article.

Authorities in Ciudad Juárez said March 14 they had discovered a further 19 bodies buried behind two houses used by drug dealers, bringing the total number of corpses found there to 33. Agents began digging behind the houses on March 1, after raiding one, confiscating 3,700 pounds of marijuana and arresting several people. All but three of the bodies appear to be men, and most have been buried at least five years. Some were dismembered. It's the second such find in less than a month: federal authorities also unearthed nine bodies buried in the yard of a Ciudad Juárez home in late February after a drug bust. (LAT, NYT, March 15)

Mexico's lower House of Deputies voted to open an investigation into accusations that Government Secretary Juan Camilo Mouriño improperly helped his family win contracts from the state oil monopoly Pemex. The accusations stem from contracts Mourino signed between 2000 and 2004 when he acted as the legal representative of his family's company while also working as a lawmaker and then as deputy energy secretary. The move comes as President Felipe Calderon, who campaigned on an anti-corruption platform, is seeking to further open Pemex to foreign investment.

More than two weeks after Colombia's military incursion into Ecuadoran territory to take out Raul Reyes, a top-ranking leader of the Revolutionary Armed Forces of Colombia (FARC), voices are being raised about possible US complicity or direction in the hit. On March 9,Simon Romero in the New York Times took a tentative stab at it, noting a similarity between the tactics of Colombian President Alvaro Uribe and his pal George Bush—e.g. Washington's nearly identical hit on supposed al-Qaeda militant Abu Laith al-Libi in Pakistan last month...
