Rock slide in Cairo shantytown kills 24 - Yahoo! News

An awful scenario: boulders the size of houses raining down on a shantytown in Cairo. AP has the details. But a significant news nugget is buried in the article:

1. "The reason the rocks keep falling is because there is no sewage system and their wastewater is eating away at the mountain," Hani Rifaat, a local journalist who has been following the issue, told AP from the site of the disaster.

2. Resident Mohammed Hussein said contractors have been working on shoring up the cliffs as they became increasingly unstable, but they could not complete their work until the government resettled the community below. "The contractor who is stabilizing the mountain asked the government to resettle everyone at least 32 miles from the mountain because he didn't want the rocks he was removing to fall on the people," Hussein told AP Television News. "The rocks are soaked with water and so are more brittle and prone to falling."

So, once again, squatters are victimized by lack of investment in infrastructure.
