Maduro's claims that Capriles will be killed by CIA

This article is part of a new talking point by Maduro, claiming that Capriles will be killed by CIA , yet Capriles said openly that if he something happens to him, that is it Maduro's doing. 

This is especially foreboding and strange because Capriles is the favorite from international bodies (non communists ones) so why on earth would Maduro find anything about Capriles' death, unless it was merely unfounded and used as a veiled threat.

Maduro on 3/16 actually shut down an airport that Capriles was using that morning.
