Officials alert foreign services that Snowden has documents on their cooperation with U.S. - The Washington Post: 
"The process of informing officials in capital after capital about the risk of disclosure is delicate. In some cases, one part of the cooperating government may know about the collaboration while others — such as the foreign ministry — may not, the officials said. The documents, if disclosed, could compromise operations, officials said.
The notifications come as the Obama administration is scrambling to placate allies after allegations that the NSA has spied on foreign leaders, including German Chancellor Angela Merkel. "
