NEW YORK — The U.S. vowed not to be intimidated by North Korean threats Tuesday after Pyongyang reportedly said it could fire a nuclear warhead if Washington did not act to resolve the standoff. [...]
The latest North Korean threat came in a report by the country's Yonhap news agency. "We hope the situation will be resolved before an unfortunate incident of us firing a nuclear missile comes," it quoted an unidentified North Korean official as saying. "That depends on how the U.S. will act."
