Abstract
It is shown that the correlations predicted by relativistic quantum field theory in locally normal states between projections in local von Neumann algebras $\cA(V_1),\cA(V_2)$ associated with spacelike separated spacetime regions have a (Reichenbachian) common cause located in the union of the backward light cones of and . Further comments on causality and independence in quantum field theory are made.
