Hidden Soviet bio-weapons still out there?

Report asks Do KGB agents, recruited by al-Qaeda, still guard the post-Soviet biological weapons hidden in Britain?

It’s like in a game "Russian roulette": nobody knows where’s the bullet and when the gun will fire a shot. During the Cold War, the Soviet intelligence hid some WMDs in the West: biological, chemical and nuclear. There’s a lot of evidence that the weapons remain in place, guarded and maintained by Russian spies. Will terrorists use them?

There's more - suitcase nukes, overpressure grenades, and .... all just in time fo Halloween.

And book sales

Nonetheless,
Hmmm.
