UNESCO Warns Thai Attacks Threaten Humanity’s Heritage as Ancient Cambodian Temples Damaged

PHNOM PENH, Cambodia (Dec. 12, 2025) — UNESCO has issued a stark warning that renewed Thai–Cambodian border clashes are endangering cultural treasures that “belong to all humanity,” after reports of military shelling damaging ancient Khmer temples.

Speaking via video link to the 32nd Plenary Session of the ICC Angkor/Sambor Prei Kuk, Lazare Eloundou Assomo, Director of the World Heritage Centre, said UNESCO is closely monitoring the situation and preparing emergency support.

He stressed that Cambodia’s Angkor era temples hold “exceptionally rich cultural value,” making any harm to them a matter of global concern, not just a bilateral dispute.

His remarks followed confirmed reports that Ta Krabey Temple and the Preah Vihear Temple complex — both revered monuments — were struck by heavy Thai weaponry during recent clashes.

UNESCO reiterated its “deep concern” first expressed Dec. 10, warning that military action against cultural heritage violates international obligations under the 1954 Hague Convention and the 1972 World Heritage Convention.

The organization urged all parties to implement protective measures and refrain from further threats to Cambodia’s sacred sites. Experts warn continued shelling risks destroying centuries old temples considered irreplaceable masterpieces of Khmer civilization. UNESCO said it stands ready to support Cambodia but emphasized that safeguarding heritage is a responsibility shared by all nations, including those engaged in conflict.
