It is shown that the correlations predicted by relativistic quantum field theory in locally normal states between projections in local von Neumann algebras \({\cal A}\)(V1),\({\cal A}\)(V2) associated with spacelike separated spacetime regions V1,V2 have a (Reichenbachian) common cause located in the union of the backward light cones of V1 and V2. Further comments on causality and independence in quantum field theory are made.
