Kuala Lumpur (Agencies): The dispute over an 11th century Hindu temple between Thailand and Cambodia continued as Phnom Penh refused to attend a Joint Boundary Commission meeting to resolve the issue.

Cambodia will put forward that it is at war with Thailand and that interference from a third party is needed when it presents its case to the UN Security Council on Monday, the Bangkok Post quoted an unnamed Government source as saying.

The country would produce proof that the Thai military had been the aggressors during the border clashes and had used prohibited weapons including cluster bombs and poison gas, the source said.

"Now bilateral mechanisms cannot resolve the issue," said Var Kimhong president of Cambodia's boundary commission.

Since border scuffles hit the country on February 4 along the Hindu Shiva temple, known as Preah Vihar, Thailand has said the dispute should be resolved with bilateral dialogues through the joint boundary commission.

Indonesian Foreign Minister Marty Natalegawa, the current Asean chair has set the meeting to be organised on February 22.

In the mean time, Thailand has said that above 20,000 soldiers will be posted on the Thai-Cambodian border as part of a national defence plan and an incident action plan approved by the army commander, Bangkok Post quoted army sources as saying on Sunday.

The decision is to remain in effect till March 30.

The main entrance of the Shiva temple known as Preah Vihar is officially on the Cambodian side but most of the other parts of the temple spread over to the Thai side.

Recent reports had said that parts of the temple had been demolished in the recent disputes between the two neighbours after Cambodian troops used the shrine as a military base to fire on the Thai soliders.

The construction of the first temple at the area started in the early 9th century and continued in the following centuries dedicated to Shiva in his manifestations as the mountain gods Sikharesvara and Bhadresvara, online reports said.

The previous surviving parts of the temple dates from early 10th century, when the empire's capital was at the city of that name. In the wake of the decline of Hinduism in the area the site was converted to use by Buddhists.

In 1954, Thai forces occupied the temple following the departure of French troops from Cambodia.

Cambodia protested and turned to the International Court of Justice which later ruled in 1962 that the temple belonged to Cambodia.
