"Signature strikes": CIA wants expanded authority for drone attacks in Yemen

The CIA is seeking authority to expand its covert drone campaign in Yemen by launching strikes against terrorism suspects even when it does not know the identities of those who could be killed, U.S. officials said.

Securing permission to use these “signature strikes” would allow the agency to hit targets based solely on intelligence indicating patterns of suspicious behavior, such as imagery showing militants gathering at known al-Qaeda compounds or unloading explosives…

For President Obama, an endorsement of signature strikes would mean a significant, and potentially risky, policy shift. The administration has placed tight limits on drone operations in Yemen to avoid being drawn into an often murky regional conflict and risk turning militants with local agendas into al-Qaeda recruits.

A senior administration official, who like others spoke on the condition of anonymity to discuss sensitive internal deliberations, declined to talk about what he described as U.S. “tactics” in Yemen, but he said that “there is still a very firm emphasis on being surgical and targeting only those who have a direct interest in attacking the United States.”
