 More recently, in 2008, another rock slide from the Mokattam hills killed more than 100 people in El-Duweiqa, another shantytown in the Mokattam district.These rock slides have brought attention to the precarious location of shantytowns located below the Mokattam mountains as well as to the Zabbaleen.Some attribute these frequent rock slides to various development and construction activities on Mokattam Mountain's upper plateau on which the upper middle class residential district of Mokattam City is located.
