  Bose-Einstein correlations in W-pair production at LEP are investigated in a
data sample of 629 pb^-1 collected by the L3 detector at centre-of-mass
energies of 189-209 GeV. Bose-Einstein correlations between pions within a W
decay are observed and found to be in good agreement with those in light-quark
Z decay. No evidence is found for Bose-Einstein correlations between hadrons
coming from different W's in the same event.
