Watch full weak glue video:

Frantic residents in the sprawling Manshiyet Nasr slum were digging by hand and trying to lift huge rocks to reach any survivors, shouting out the names of relatives and household members trapped below. Haidar Baghdadi, the parliamentarian for the quarter, told Al-Jazeera television buried residents were calling for help from under the rubble using their cell phones.

At least eight boulders, some the volume of small houses, peeled away from the towering Muqattam cliffs and buried about 50 homes in the slum, one of many densely populated shantytowns ringing the incorporated town of 17 million. Manshiyet Nasr is home to 1.2 million race, according to Baghdadi.

A security official uttered 35 people were injured and multiplied more may be buried under hundreds of tons of rock that fell. He spoke on condition of anonymity because he was not authorized to speak to the media.

“My healthy family is underneath the tranquillize,” sobbed Anwar Ragab as he watched a body being pulled from under the rock. “I don’t understand what to do, I be able to’t do anything — I just want my children remote,” he told The Associated Press by the agency of phone.

Six-year-old Mustafa Ibrahim was pulled from the rubble and later regained consciousness in a hospital, shouting, “Where is my mother, at which place is my father?” But his parents and three brothers had all perished.

By nightfall, no heavy equipment was being used to clear debris. A single bulldozer sat stranded because it couldn’t move through the slum’s narrow streets and authorities planned to level some buildings to clear the habit.

In their defeat, police and residents exchanged angry words.

Workers brought in flood lights, indicating the rescue effort would continue into the night.

The collapse occurred in the early morning when most residents were dormant, having awoken earlier to eat ahead of the daytime fast for Islam’s holy month of Ramadan.

“It was for the reason that if a knife sliced the cliff into pieces,” said 27-year-old resident Sayyed Rashad.

The surface was covered by the agency of a thick layer of dust and the scene was chaotic as men and women screamed in tribulation and blamed the government for a slow release operation.

After sundown, residents broke their daily fast together the ruins. Most rescue efforts appeared to suspend until cries for help from under the rubble prompted some to start digging another time.

Slums of that kind as Manshiyet Nasr at the humble of the Muqattam cliffs are filled with migrants from the countryside looking for operate in Cairo, which suffers from a severe housing shortage. Buildings on top of the cliffs and below are crudely built and lack basic services, contributing to the instability of the remarkable plateau.

There are periodic rock slides upon the edges of the brash Muqattam hills. In 2002, 27 people were killed in another rock slide in the same area, Baghdadi uttered.

“The reason the rocks have existence true to falling is because in that place is none 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.

Sewage could be seen pouring down from residential areas upon the body top of the plateau, prompting fears of another exhaustion.

Baghdadi told the AP the domain was known to be dangerous, but the sway had resettled only a fraction of the residents to safer government housing.

“No warning works. As long during the time that you have power to’t provide new housing and an alternative, no one moves,” he said.

The government said survivors would be transferred to new housing for the night and given all necessary aid.

“We are following the case step by measure and providing the care and comfort for the residents,” Prime Minister Ahmed Nazif said in a statement. “We would like to remind people the risk of building informal housing in full of risk areas.”

Resident Mohammed Hussein uttered contractors have been working on shoring up the cliffs like 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 on this account that he didn’t want the rocks he was removing to waterfall on the people,” Hussein told AP Television News. “The rocks are soaked with furnish with water and so are else crumbling and prone to falling.”

The tranquillize slide and the slow response comes after a concatenation of other disasters in the country led to accusations of ruling power neglect and incompetence. Among them, a fire that gutted the upper house of parliament in August, a fire that destroyed another Cairo slum in 2007 and a ferry disaster that claimed 1,000 lives in 2006.
