Two global newspapers say documents provided by former NSA contractor Edward Snowden raise questions about whether British intelligence played a role in a 2012 U.S. drone strike in Yemen.

The Guardian and The New York Times suggested Wednesday that the documents indicate British intelligence may have provided useful information to American agencies before the drone strike, which took place outside a recognized war zone.

The documents are said to show the extremely close cooperation between the NSA and its British counterpart, the Government Communications Headquarters better known as GCHQ, in regards to the controversial drone program.

British officials have refused to comment on the report or give details about any involvement in the U.S. drone program, which has been used to target terror suspects in Yemen and elsewhere.
