These results are based on a 23.6 fb^{-1} data sample collected with the Belle detector on the \\Upsilon(5S) resonance at the KEKB asymmetric-energy e^{+}e^{-} collider, containing 1.25x10^6 B_{s}^{(*)}\\bar{B}_{s}^{(*)} events. We observe the decay B_{s}^{0}->K^{+}K^{-} and measure its branching fraction, \\mathcal{B}(B_{s}^{0}->K^{+}K^{-}) = [3.8_{-0.9}^{+1.0}(\\mathrm{stat})\\pm 0.5(\\mathrm{syst})\\pm 0.5(f_s)] \\times 10^{-5}.
