Claim Pakistan 'supports Taliban'

Allegations that Pakistan has actively been supporting Taliban insurgents, while acting as an ally of the US in public, have been made to a BBC investigation.

Last week Pakistan said it could do more to prevent militant groups operating within its borders, but the allegations suggest Islamabad has been secretly backing the Taliban.

Pakistan denies the allegation.
