From the analysis of the reactions e+e-→l+l- (nγ) (l=e,μ,τ) we observe four events, one e+e-γγ and three μ+μ-γγ, with the invariant mass of the photon pairs close to 60 GeV. These events were selected from a data sample collected in the L3 detector corresponding to 950 000 produced Z0 s. More data are necessary to ascertain the origin of these events.
