Bangkok , Thailand ( CNN ) -- Clashes over a disputed area along the Thai-Cambodian border erupted for a fourth consecutive day Monday , resulting in the death of a Thai soldier , a military official said . Four other Thai soldiers have been killed since the fighting started Friday , according to Col. Sansern Kaewkumnerd . Authorities have evacuated thousands of people from nearby villages . Each side blames the other for the violence , which first broke out last week near two temples in the Phanom Dong Rak district of Thailand 's Surin province . Cambodia 's government has said three of its troops have been killed . On Monday , Sansern accused Cambodians of trying to seize two ancient temples , Ta Kwai and Ta Muen Thom . The fighting on the ground has been coupled with a war of words in recent days . On Sunday , Sansern accused Cambodian troops of opening fire first and said Thai troops responded to protect their country 's sovereignty . Cambodian officials could not be immediately reached for comment . A statement from the country 's defense ministry Saturday described the clashes as an `` assault by Thai infantry units , '' accusing Thailand of flying spy planes into Cambodia and attacking with heavy weapons . Thailand 's foreign ministry issued statements Saturday accusing Cambodia of `` firing heavy weapons at innocent Thai civilians . '' U.S. Secretary of State Hillary Clinton said Monday that the United States `` remains deeply concerned about clashes between security forces along the Thailand-Cambodia border . '' The U.S. government is speaking directly to Thai and Cambodian officials , and also supports efforts by Indonesia , the chair of the Association of Southeast Asian Nations , to work with both countries on a resolution , Clinton 's statement said . In February , at least 10 people were killed when fighting flared up in another disputed border area between the two nations , prompting the United Nations Security Council to issue a statement calling on both sides to implement a cease-fire . Those clashes , which lasted four days , stemmed from a longstanding conflict related to the 11th-century Preah Vihear temple . Both Cambodia and Thailand lay claim to the temple , which sits atop a cliff on Cambodian soil but has its most accessible entrance on the Thai side . At the time , each nation accused the other of firing first . CNN 's Kocha Olarn contributed to this report .
