SEOUL/WASHINGTON (Reuters) - The United States warned on Tuesday it would consider "other" options, which could include new sanctions or security steps, if North Korea continued nuclear and ballistic missile testing.South Korea's Yonhap news agency earlier said North Korea appeared to be preparing a test-launch of an intermediate-range ballistic missile, after what the United States described as the "fiery, catastrophic" failure of a launch attempt this month.
It is widely expected to conduct a fifth nuclear test soon, perhaps ahead of a congress of the ruling Workers Party congress in early May.
