Venice could lose its status as a World Heritage Site if it does not adequately protect itself from worsening flooding, UNESCO representatives have warned as they offered help after recent inundations.

¡°Key buildings which are within the World Heritage area are threatened. ... This is of great concern to us, especially as this is not a single incident,¡± said Mechtild Roessler, director of the World Heritage Center.

Venice suffered heavy damage when floodwaters reached one of the highest levels in more than 50 years this month.
