We report a search for the decays B0→K*0K ̄*0 and B0→K*0K *0. We also measure other charmless decay modes with K +π-K-π+ and K +π-K+π- final states. The results are obtained from a data sample containing 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e +e- collider. We set upper limits on the branching fractions for B0→K*0K̄*0 and B0→K*0K*0 of 0.81×10 -6 and 0.20×10-6, respectively, at the 90% confidence level.
