Colombian officials say they are ordering an investigation into a report by the country's leading news magazine that members of an elite army cyber-unit spied on the digital communications of the government team negotiating peace with FARC rebels.

Interior Minister Aurelio Iragorri said Tuesday in a radio interview that President Juan Manuel Santos' government did not authorize the espionage.

Semana magazine late Monday posted a story online saying the collection of emails as well as text and Blackberry messages from government negotiators in the Havana talks began in September 2012 and ended in October.

The story says voice communications were not intercepted but email accounts and cellphone PINs were hacked.
