The United States has thrown its support behind the efforts of Indonesia to mediate in the deadly border clashes between Thai and Cambodian forces.
Secretary of State Hillary Rodham Clinton said Monday the U.S. was deeply concerned about the violence. In a statement, she urged both sides to exercise restraint and act to reduce tensions.
Four days of clashes have killed at least 12 soldiers and displaced nearly 50,000 people on both sides of the border.
Clinton said U.S. officials were talking with both countries, and Washington supported efforts of Indonesia as current chairman of the Association of Southeast Asian nations to help reach a resolution.
Thailand has rejected outside help, saying the two countries have to resolve the dispute alone.
