The JANZOS Collaboration has reported a 2-day burst of TeV {gamma} rays from SN 1987 A 11 months after the explosion. At this supernova epoch TeV {gamma} rays can only be produced by inelastic proton interactions and secondary {pi}{sup 0} decay. The proton luminosity during the burst has to be 2{times}10{sup 39} ergs/s, in contradiction with the most recent estimates of the total power of an internal energy source. We suggest a burst model where the TeV {gamma}-ray burst is produced by a previously accumulated proton beam, which is in agreement with the observed energetics of SN 1987A in all observation bands.
