US defense secretary Robert Gates has warned North Korea that Washington would not accept it as a nuclear-armed state. His comments at a security conference in Singapore came after Pyongyang tested a nuclear device and short-range ballistic missiles this week. Tensions continue to grow in the region, with signs that North Korea could be preparing to test a long-range missile.
