Afghanistan drawdown: Bereaved father honours fallen UK troops

The UK has officially ended ground operations in Afghanistan, bringing the 13-year mission to an end.

The forces were part of a US-led coalition which toppled the ruling Taliban in 2001, following the 9/11 attacks.

The number of British troops who died during the conflict stands at 453.

Among them was Private Conrad Lewis of 3 Para who was killed by a Taliban sniper on February 9, 2011.

The BBC's Fergal Keane travelled with Tony Lewis as he went to Afghanistan to see where his 22-year-old son died.

While there, Tony Lewis laid a wreath to fallen British troops at the British cemetery in Kabul.
