US officials meanwhile have acknowledged the CIA has been launching drone attacks in Pakistan despite often not knowing the identities of its targets. The strikes have been carried out under widely expanded authority approved by the Bush administration two years ago. The policy means the CIA’s targets can extend far beyond what was previously a narrow list of suspects. The Los Angeles Times reports the identities of the vast majority of over 500 victims killed under the expanded authority were unknown or subject to fragmentary information. In some cases, the CIA learned it had targeted a known terror suspect only after the suspect turned out to have been killed.
