Also: Terror Suspects Freed Due To Lack Of Evidence

Over 70 workers at Paris' Charles de Gaulle airport have been denied access to sensitive areas of the airport on security fears. Authorities say they pose a risk to passengers, because of their ties to international terrorism.

Police eyed over 100 baggage handlers and aircraft washers for the past few months... during which time some of them allegedly visited terrorist training camps in Pakistan and Afghanistan.

In an interview with the Associated Press, airport official Jacques Lebrot claimed the crackdown was "linked to terrorism," and that it came after France's anti-terrorism coordination unit, UCLAT, recommended such measures as part of an 18-month investigation.

Investigators said one individual is close to terrorists with links to al Qaeda... and another was friends with shoe-bomber Richard Reid.

Terror Suspects Freed

Meanwhile, two brothers originally charged in connection with theAugust bomb plot against US-bound airliners flying from London have been freed, after authorities say they don't have enough evidence to bring them to trial.

Mehran Hussain, 24, and Umair Hussain, 25, were accused of not disclosing information about their brother Nabeel, who is still in custody in connection with the alleged conspiracy.  The two men have refused to comment publicly about their arrest -- and subsequent release -- unless their brother is also released.

A new FBI report now suggests the terror suspects planned to blow those airliners up over US cities, using liquid explosives brought onboard carryon luggage, to maximize casualties... instead of over water as originally thought.
