We report on a search for charmless hadronic B decays to the three-body final states KS0h+π-, K+h-π0, KS0h+π0 (h± denotes a charged pion or kaon), and their charge conjugates, using 13.5 fb-1 of integrated luminosity produced near sqrt[s]=10.6 GeV, and collected with the CLEO detector. We observe the decay B→K0π+π- with a branching fraction (50-9+10(stat.)±7(syst.))×10-6 and the decay B→K*+(892)π- with a branching fraction (16-5+6(stat.)±2(syst.))×10-6.
