ABOARD A U.S. MILITARY JET -- U.S. Defense Secretary Robert Gates says the United States is not planning to send more troops to the Korean peninsula despite this week's nuclear and missile tests by North Korea.
Gates says he hasn't seen any unusual moves by the North Korean military since the weapons tests to warrant a buildup of U.S. forces in South Korea. The U.S. has about 28,000 troops stationed in South Korea.
Gates says the situation has not reached a crisis level. But he calls the weapons tests, in his words, "provocative" and "accompanied by very aggressive rhetoric."
Gates spoke to reporters aboard a military aircraft as he headed to a meeting of Asian defense ministers in Singapore.
