Afghanistan drawdown: Tony Lewis arrives in Kabul

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 pay tribute to his 22-year-old son and his fallen colleagues.

On arriving in Kabul, Mr Lewis shared his thoughts about arriving in the land where Conrad died.
