Witnesses in Burma have detailed the construction of a secret nuclear site deep in a jungle north of Rangoon, the latest WikiLeaks cables reveal. One witness saw North Korean technicians blowing concrete into an underground site, while another spotted a barge full of reinforced steel too large to be used in a factory. Dock workers have reported loads of suspicious cargo. As many as 300 North Koreans are rumored to be working at the site. The international community has long suspected Burma of harboring nuclear ambitions. The details raise the alarm about the effects of North Korea's nuclear capabilities ending up in the hands of rogue states.
