The United States began a round of controversial underground nuclear weapons-related tests on Wednesday in the Nevada desert, an Energy Department spokeswoman said.
The experiments, announced earlier, were designed to test weapons materials without triggering the kind of nuclear chain reaction prohibited by the international treaty signed last year. REUTE
