Russia's new approach to dealing with "extremists"

[Aenlic]

Several employees of the Millenium hotel have tested positive for non-lethal (supposedly) exposure to polonium-210. This pretty much narrows down the location of the event to that hotel. It was here that Litvinenko met with the ex-agents, Kovtun and Lugovoi. It now appears that Kovtun was exposed and is possibly ill from the same source. So, that leaves several questions:

Were Kovtun and Lugovoi the assassins? If not were they targets or merely exposed unintentionally or perhaps set up to look like the assassins?
