(CNN) - U.S. Secretary of State Hillary Clinton said Friday that North Korea must faces consequences after a report that it fired a torpedo that sank a South Korean warship in March.
"I think it's important to send a clear message to North Korea that provocative actions have consequences," she said amid heightened tensions and a diplomatic war of words between Seoul and Pyongyang over the incident. "We cannot allow the attack on South Korea to go unanswered by the international community."
Clinton was speaking in Tokyo, Japan, for the first leg of her week-long tour in Asia. She said she was consulting with international allies to find the appropriate reaction.
North Korea threatened to back out of a nonaggression pact between the nations, while the South Korean president accused its northern neighbor of engaging in military provocation, South Korea's Yonhap news agency reported on Friday.
