Taliban fighting 'has wrecked children's education'

More than half a million children in Pakistan are left with little hope of education after clashes between the army and Taliban destroyed hundreds of schools, according to the United Nations.

The offensive in the North West Frontier Province (NWFP) led to one of the largest internal displacements in recent years as around 2.3 million people left their homes, many after fighting worsened in April.
