The operation also resulted in severe damage to the historic core of the city, with 64 heritage buildings being heavily damaged or destroyed. IDF forces reentered Nablus during Operation Determined Path in June 2002, remaining inside the city until the end of September. Over those three months, there had been more than 70 days of full 24-hour curfews. According to Gush Shalom, IDF bulldozers damaged the al-Khadra Mosque, the Great Mosque, the al-Satoon Mosque and the Greek Orthodox Church in 2002. Some 60 houses were destroyed, and parts of the stone-paving in the old city were damaged. The al-Shifa "hammam" was hit by three rockets from Apache helicopters. The eastern entrance of the Khan al-Wikala (old market) and three soap factories were destroyed in F-16 bombings. The cost of the damage was estimated at $80 million US.
