BERLIN (AP) - Germany's chancellor says U.S. intelligence was key to foiling a large-scale terror plot, acknowledging her country is "dependent" on cooperating with American spy services.
But Angela Merkel also told broadcaster RTL on Monday that she was "surprised" to learn of the scope of recently leaked U.S. spying programs.
Merkel said the U.S. must clarify what information on people's communications is monitored and how, reiterating that she will raise the issue in talks with President Barack Obama in Berlin on Wednesday.
However, Merkel said security services could have not foiled a 2007 terror plot without "tips from American sources."
Four Islamic extremists were then arrested while preparing an explosive device with power equivalent to 900 pounds of TNT that authorities said was meant to attack American soldiers and citizens in Germany.
