Renegade Afghan soldier 'sheltering with Taliban'

The Taliban says it is sheltering a renegade Afghan soldier who attacked British troops at a base in Helmand province.

Three soldiers, from 1st Battalion The Royal Gurkha Rifles, were killed and another four injured in the attack.

The incident has further highlighted the challenges in training Afghan security forces so foreign units can return home.
