  Using a data sample of 10.5 1/fb collected by the Belle detector, three-body
charmless decays B+ --> K+h+h- have been studied. The following branching
fractions have been obtained: Br(B+ --> K+pi-pi+) = (64.8+-10.0+-7.0) x 10**-6
and Br(B+ --> K+K-K+) = (36.5+-6.1+-5.5) x 10**-6. The upper limits for other
combinations of charged kaons and pions have been placed. Analysis of the
intermediate two-body states gives evidence for production of scalar resonances
in charmless B decays.
