Bangkok , Thailand ( CNN ) -- Thai officials on Wednesday pulled out of planned cease-fire talks with Cambodia , hours after fighting flared up again in a bloody border dispute that has sent tens of thousands fleeing over the past week . About 27,000 people are living in shelters in Thailand , the nation 's health ministry said . A Thai army spokesman said the two nations had planned meetings between their defense ministers to discuss a cease-fire . `` But before our departure yesterday , some Cambodian media misreported that our trip to Cambodia was to surrender because we were defeated , '' said Col. Sansern Kawekumnerd , the spokesman . `` So the minister thought that if we continued our trip to Cambodia today , it will bring wrong messages to Cambodia and the international community . '' But the negotiation door is not closed , the spokesman said . He accused Cambodia of firing again on Tuesday night , and urged the nation to halt attacks `` to show their honesty of going back to negotiation table . '' The spokesman said Cambodians unsuccessfully attempted to seize Ta Muen and Ta Kwai temples on Tuesday night , leaving one civilian dead . Thailand calls the temples Ta Kwai and Ta Muen , while Cambodia calls them Ta Krabey and Ta Moan . Much of the border between the two countries remains in dispute . Both sides claim the disputed temples are in their country . Clashes between the two started Friday as they accused each other of trying to seize the ancient temples . Thai officials say at least six of its citizens have died and more than 40 injured in the clashes over the past week . Cambodia has said three of its troops have been killed in the fighting . 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 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 . CNN 's Kocha Olarn contributed to this report .
Fresh clashes break out as talks collapse , a Thai official says . Thailand says 27,000 people are living in shelters . The government has been under pressure to do more for the refugees since it opened its doors last week and said that up to 10,000 could be housed by Thursday.
