Amid Israel's targeted land seizures and ongoing military offensives, the Mount Amel Castles in Lebanon and the archaeological ruins of Sebastia in the Occupied West Bank are among six new locations that were urgently added to UNESCO's list of World Heritage Sites in Danger this week. The international agency immediately recognized both locations as vulnerable upon inscribing them as World Heritage Sites at the World Heritage Committee's 48th session in Busan, South Korea. Israel condemned the designations, accusing UNESCO of “cynical exploitation of cultural heritage for political purposes.”
