SEOUL (Reuters) - The United States and its ally South Korea were discussing on Monday sending more strategic U.S. weapons to the Korean peninsula, a day after a U.S. B-52 bomber flew over South Korea in response to North Korea's nuclear test last week.

North Korea said it set off a hydrogen bomb last Wednesday, its fourth nuclear test since 2006, angering China, the North's main ally, and the United States, which said it doubted the device was a hydrogen bomb.
