Peshawar teacher: Dead son 'was just smiling'

Children have been going back to the army public school in Peshawar, Pakistan, where at least 150 people were killed in an attack by Taliban gunmen last month.

For one of the teachers, Andaleeb Aftab, it will be a particularly poignant and difficult day as her son was killed in the attack.

She spoke to the BBC's Shaimaa Khalil about the day of the attack and how she felt about coming back to work.
