More than 30 students killed in Pakistan school roof collapse

The number of people killed in a school roof collapse continues to rise in northwest Pakistan. At least 34 children and one teacher are dead. A frantic rescue effort is ongoing. Locals were among the first to reach the school in the congested neighborhood. Rescue crews are now digging through the debris, trying to reach kids and staff feared trapped under the collapsed roof. Anna Cunningham now with the latest on the rescue, Anna. David, there is real anger in Peshawar from parents who are desperately searching for their children. They are saying this should never have happened. This school was three stories high, but if you look at the images, you can see that it was built into a narrow alleyway into a crowded street. Police say they believe some 115 students were inside these classrooms when the roof caved in, and it appears to have really catastrophed from one level to another. We know that all the school children were told, are believed to have been aged 13 and under. Right now, the location is actually making rescue efforts even more tricky because just one small ambulance can get by at any time. And on the inside, that's where people have been digging. They've been using spades, trying to shift that debris. There was a local man who said that they pulled out between 10 and 15 children, who he says were buried up to their necks. Police say that the owner of the school he is in police custody. There is an initial report into allegations now of substandard building materials used, and we know that's something that's not uncommon in Pakistan. Building regulations are poorly enforced in the country. We have also been seeing images come out from outside the hospital. That's where families are gathering. They're now hoping for news of their children as the injured are brought in. David.
