Article mentions seizure of red mercury (https://en.wikipedia.org/wiki/Red_mercury) which suggests that either the writer is incredibly misinformed or this is an intentional disinfo piece.
I'm also pretty skeptical about this story to be honest, but FWIW it was repeated by the BBC. http://www.bbc.com/news/world-europe-43463195 The link I submitted is the nearest I can find to an original source.
The truth is probably either that a smaller amount of californium was seized (possibly 1.4g) or the californium was part of a 1.4kg assembly including some other elements.
Implausible amounts of Californium, nonsense about red mercury, the bit about Al... it reeks.
