dc.description	The B -> D^{()} K^- K^{()0} decays have been observed for the first time. The branching fractions of the B -> D^{()} K^- K^{()0} decay modes are measured. Significant signals are found for the B -> D^{()} K^- K^{0} and B^- -> D^0 K^- K^0_S decay modes. The invariant mass and polarization distributions for the K^-K^{0} and K^-K^0_S subsystems have been studied. For the K^-K^{0} sybsystem these distributions agree well with those expected for two-body B -> D^{()} a_1^-(1260) decays, with a_1^-(1260) -> K^- K^{0}. The analysis was done using 29.4 fb^{-1} of data collected with the Belle detector at the e^+ e^- asymmetric collider KEKB.
