Rogers claims al Qaeda tipped off by Snowden -

Mike Rogers, the chairman of the House Intelligence Committee, claims that al Qaeda has changed the way it communicates in the light of Edward Snowden's leaks.

Talking to CBS's Face the Nation, Rogers said if Snowden disclosed classified information that has allowed three different terrorist organisations, affiliates of al Qaeda to change the way it communicates.

Rogers was evidently referring to an intelligence analysis of the impact of Snowden's leaks

The former contractor leaked to the press, as well as foreign governments, various National Security Agency files, as well as descriptions of the agency's surveillance programmes.

Intelligence officials have so far differed in their assessments of the damage done by Snowden, with respect to the fight against al Qaeda.

Matthew Olsen, the director of the National Counterterrorism Centre, thinks al Qaeda has been adapting to the revelations.

Others think that the release of sensitive communications between al Qaeda emir Ayman al Zawahri and his subordinates in early August has done more damage.

While it is suspected that Al Qaeda has been tracking the leaks of classified information very closely, it must be thinking a lot of it is old news. The terror group has changed the way it behaved after Osama bin Laden's lair was raided.

Thousands of formerly classified American intelligence reports from the battlefields of Afghanistan were found in in Abbottabad, Pakistan.

Either way it looks like Rogers is trying to turn public opinion against Snowden by pulling out an old bug-bear. . So far, Snowden leaks have not really covered al Qaeda and mostly deal with the NSA snooping on its own citizens and allies.
