We report results on the Dalitz analysis of three-body charmless B+ {yields} K+{pi}+{pi}-, B0 {yields} K0{pi}+{pi}- and B+ {yields} K+K+K- decays including searches for direct CP violation in B+ {yields} K+{pi}+{pi}- mode. Branching fractions for a number of quasi-two-body intermediate states are reported. We also observe 3.9{sigma} evidence for a large direct CP violation in B{+-} {yields} {rho}(770)0K{+-} channel. This is the first evidence for CP violation in a charged meson decay. The results are obtained using Dalitz analysis technique with a large data sample of BB-bar pairs collected with the Belle detector operating at the KEKB asymmetric energy e+e- collider.
