A young girl, badly wounded by a stray grenade in Afghanistan, has finally returned home after treatment in the United States.

Seven-year-old Shah Bibi took the full force of the blast in an area where villages are frequently caught in the crossfire between the Taliban and Afghan Army.

It is the same region where just last week two western female journalist were shot - one of them fatally.

The BBC's Karen Allen has been following Shah Bibi's progress.
