The World Heritage Committee may also specify that a site is endangered, citing "conditions which threaten the very characteristics for which a property was inscribed on the World Heritage List." Along with other World Heritage Sites, sites in danger are subject to re-evaluation by the committee every year at their "ordinary sessions". Africa has 17 sites on the danger list, accounting for 13% of all African sites and 35% of the 48 endangered sites worldwide. The Democratic Republic of Congo and Libya both have 5 sites on the danger list, the second highest of any country in the world and two of the three countries to have more than three sites inscribed.
