A section of wall around an ancient shop in Pompeii is the latest casualty of rain in one of Italy's most popular archaeological sites.

Pompeii's archaeological office said Monday a section of the recently restored wall had collapsed. The damage is in an area long closed to the public, at the edge of the excavations of the ancient Roman city. Officials said inadequate drainage in the unexcavated part is particularly worrisome. Rains lashing the Naples area recently were also blamed for damage discovered Sunday in other parts of Pompeii.

Italy's culture minister has summoned top Pompeii officials to Rome Tuesday to evaluate progress in efforts to safeguard the archaeological ruins of the flourishing city that was devastated by the of Mount Vesuvius in 79 AD.
