Colombian President Juan Manuel Santos says he's seeking clarification from Washington on whether its intelligence-gathering in his country exceeded joint operations against drug traffickers and illegal armed groups.

The Associated Press asked Santos in an interview about revelations in documents leaked by U.S. intelligence contractor Edward Snowden showing that massive U.S digital data collection has targeted allies as well as foes.

Santos said U.S. Vice President Joe Biden had called him about the matter.

Asked if he was satisfied with Biden's explanations Santos replied curtly, saying, "We are in that process."

Santos was previously defense minister and has been among Colombian officials who heartily welcomed U.S. technical support in electronic eavesdropping.

Santos will host U.S. Secretary of State John Kerry during a one-day visit that begins Sunday night.
