The Iranian government is significantly boosting its presence and resources in Latin America, posing a national security threat to the region, according to a group of U.S. and Latin American officials who met earlier this week in Florida to discuss Iran's covert actions.

While Iran has long had a foothold in the Western hemisphere, these officials warned that the Islamic Republic has invested significant resources into its Latin American operations in a bid to increase its sway in the region.

Iran's growing influence in the region—and its effort to exert influence over governments there—has fostered pressing security concerns as the Iranians inch closer to the United States' southern border, according to these U.S. officials and Latin American leaders, who met for several days this week at a summit organized by the Israel Allies Foundation (IAF).
