UK spy chief defends secrecy in 1st public speech

LONDON — Britain's spy agency chief stepped out of the shadows with an unprecedented public address Thursday, defending the need for secrecy to counter growing terror threats such as Iran's nuclear proliferation.
MI6 chief John Sawers said even though Cold War-era secrecy has been lifted and intelligence agencies were working to become more accessible keeping intelligence material secret was vital to protect people against terror attacks.
