MARDAN , Pakistan ( CNN ) -- Inside a hospital ward in northwest Pakistan , I found myself surrounded by sobs and screams . One scream was so high-pitched that I did n't think it was human . These were the sounds of agony , and they belonged to innocent civilians who were injured in the cross fire of Pakistani troops and the Taliban in the Swat Valley . CNN 's Reza Sayah with Shaista , who lost most of her family in an explosion as they fled fighting . Behind each cry at this ward was a story of loss . Doctors told me no one here had lost more than Shaista , an 11-year-old girl who watched as an explosion instantly killed most of her family . Shaista and her family were among hundreds of thousands of people who fled Pakistan 's Swat Valley on the day the Pakistani Army launched an all-out offensive against the Taliban . She says she was walking along a road with her family when a mortar shell suddenly fell from the sky . `` We were coming , '' Shaista told me , `` then my mother died , my brother died , and my two sisters also died . '' Watch Reza Sayah 's interview with Shaista » . Doctors said the explosion shattered Shaista 's foot . Moments later she passed out . The next time she woke up she was in the female orthopedic ward of the GHQ Hospital in Mardan . Doctors said Shaista will recover from her shattered foot , but the trauma of losing a family will last a lifetime . `` She kept saying it all happened in front of me , '' said Salma Shaheen , a nurse . `` She said something fell on top of my mother and she got cut in half . '' It was clear that Shaista had won over the hearts of the doctors and nurses who said that they , in three days , had treated more than 800 civilians injured in the battle zone . Like many hospitals in northwest Pakistan , this one was under equipped . To hold an elderly woman 's broken leg together , doctors had made a make shift traction using a brick , a plastic shopping bag and rope . Watch Reza Sayah 's report from inside the hospital » .

Her only guardian is her uncle , Muhammad Sher , who found Shaista after searching area hospitals . `` I 'm just going to tell her , 'you 're my daughter , ' '' said Muhammad . `` I 'm going to educate her , teach her the Koran and do what I can for her . '' Sixty miles away from the hospital , the battle between Pakistani troops and the Taliban raged on . On Wednesday General Athar Abbas , the army 's top spokesman , told CNN the troops were making significant progress but the most intense stage of the fighting in the battle zones ' most populated areas was still to come -- a near guarantee of more sobs and screams at area hospitals .
