Journalists team up to disclose NSA role in 'assassination programme'
'Dirty Wars' author and Snowden collaborator pledge to disclose secret role of US spy agency

Two American journalists known for their investigations of the US government have teamed up to report on the National Security Agency's role in what one called an "assassination programme".
The journalists provided no evidence of the purported programme at the news conference, nor details of who it targeted.
Jeremy Scahill, a contributor to The Nation magazine and best-selling author of Dirty Wars, will be working with Glenn Greenwald, the Rio-based journalist who has written stories about US surveillance programmes based on documents leaked by former NSA contractor Edward Snowden.
Scahill spoke to moviegoers in Rio de Janeiro, where the documentary based on his book was given its Latin American premiere at the Rio Film Festival.
He said: "The connections between war and surveillance are clear. I don't want to give too much away.
"But Glenn and I are working on a project right now that has at its centre how the National Security Agency plays a significant, central role in the US assassination programme.
