The head of the United Nations cultural agency says a preliminary assessment of the famed World Heritage site around Nepal's capital is a "huge disaster" after this weekend's earthquake.

The agency says that an expert team will see whether the structures can be repaired or even reconstructed.

UNESCO chief Irina Bokova told The Associated Press in a brief interview Monday that it was heartbreaking to see the destruction.

She says three of the seven places of worship in the extensive site in and around Kathmandu have been severely damaged.

Bokova says Nepal's other World Heritage site, a natural park around Mount Everest, is damaged, but the extent is not known.
