We report a search for the decays B{sup -}{yields}K{sup +}{pi}{sup -}{pi}{sup -} and B{sup -}{yields}K{sup -}K{sup -}{pi}{sup +}, which are highly suppressed in the standard model. Using a sample of (467{+-}5)x10{sup 6} BB pairs collected with the BABAR detector, we do not see any evidence of these decays and determine 90% confidence level upper limits of B(B{sup -}{yields}K{sup +}{pi}{sup -}{pi}{sup -})<9.5x10{sup -7} and B(B{sup -}{yields}K{sup -}K{sup -}{pi}{sup +})<1.6x10{sup -7} on the corresponding branching fractions, including systematic uncertainties.
