The measurement of the partial rate asymmetries for various B → Kπ decay modes is presented. A significant asymmetry is measured for the decay mode B → K⁺π^- with A_CP = -0.101 ± 0.025 ± 0.005 which has a significance of 3.9 σ and thus indicates evidence for direct CP violation. Furthermore the first observation of the decay mode B → π⁰π⁰ with a branching fraction of {B}(B -> π ^{0π ^0)} = (2.3_-0.5^+0.4 ± 0.2) × 10^-6 having a significance of 6.0 σ is presented accompanied with the first measurement of the CP asymmetry in this mode.
