An Improvised Explosive Device (IED) was discovered yesterday in a Buenos Aires venue slated to host former Colombian president Alvaro Uribe (2002–2010). The device was found at the Gran Rex Theater, where Mr. Uribe was scheduled to speak at a conference promoting dialogue between public- and private-sector leaders on innovation. According to the judge in charge of the case, Norberto Oyarbide, “the symposium will still take place and former president Uribe will attend.”

Uribe’s administration is generally credited with greatly reducing violence stemming from Colombia’s decades-long conflict with left-wing guerilla forces, but his hardline approach has also left him vulnerable to allegations that his administration had ties to paramilitary forces and authorized actions that resulted in widespread human rights violations. Allegations have also surfaced that, on Uribe’s watch, Colombia’s Department of Administrative Security (DAS) undertook widespread illegal wiretapping on opposition figures, politicians, judges and journalists.

Yesterday’s discovery comes only days after an assassination attempt against Uribe’s former Interior Minister, Fernando Londoño, which left two dead and dozens injured. Londoño is a vocal supporter of current President Juan Manuel Santos’ “Legal Framework for Peace,” a bill that would provide benefits for demobilized paramilitaries and guerrillas and even permit them to run for public office.

According to numerous news sources,  last week’s attack was likely carried out by remaining factions of the Fuerzas Armadas Revolucionarias de Colombia (FARC), who oppose ongoing peace negotiations.
