(CNN) -- Three bullet-riddled bodies were found in northwest Pakistan on Sunday with letters attached to them stating they were killed for being spies, two Pakistani security officials told CNN.
The bodies were in the town of Miranshah in North Waziristan. The notes claimed they were "spies" for the U.S. and Pakistani militaries, the officials said.
They did not want to be named because they are not authorized to speak to the media.
North Waziristan is one of seven districts in Pakistan's volatile tribal region bordering Afghanistan.
