Nuclear capabilities

China expanding its nuclear capabilities, scientists say

Satellite images from Xinjiang province in the west of the country suggest it is building a nuclear missile silo field, a report from the Federation of American Scientists (FAS) says.

US defence officials have expressed concern about China's nuclear build-up.

It is the second new silo field reported to be under construction in western China in the last two months.

The site could house about 110 silos, which are underground facilities used for the storing and launching of missiles.
