I came across this website which states that Sikh Gurus believe in Vedas. I cannot find the interpretations of the shabads in relation to it's comments.

On the other hand I came across this booklet which says Sikh Gurus did not believe in Vedas.

Can anyone explain what Guru Sahibaans take on Vedas was and why there are pro-Veda shabds and anti-Veda shabds in Gurbani? And how would you refute someone saying Sikh is a branch of Vedic dharam?
