description: Using a data sample of $772 \times 10^6$ BB pairs collected on the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we report the observations of $B^0\to p{\bar p}π^+π^-$ and $B^+ \to p{\bar p}π^+π^0$. We measure a decay branching fraction of $(0.83 \pm 0.17 \pm 0.17) \times 10^-6$ in $B^0\to p{\bar p}π^+π^-$ for $M_{π^+π^-} &lt; 1.22 GeV/c^2$ with a significance of 5.5 standard deviations. The contribution from $B0 \to p{\bar p}K^0$ is excluded. We measure a decay branching fraction of $(4.58 \pm 1.17 \pm 0.67) \times 10^-6$ for $B^+ \to p{\bar p}π^+π^0$ with $M_{π^+π^0} &lt; 1.3 GeV/c^2$ with a significance of 5.4 standard deviations. We study the difference of the $M_{p{\bar p}}$ distributions in $B^0\to p{\bar p}π^+π^-$ and $B^+ \to p{\bar p}π^+π^0$.
