  We discuss the status of analyses of data recorded in the 2008 and 2009 runs
of the COMPASS experiment at CERN with sepcific focus on final states with
$K^0_S K^0_S \pi^-$ and $K^+K^-\pi^-$ produced in $\pi^-(190\,\textrm{GeV})p$
scattering. The interest in such final states is motivated by a summary of some
of the relevant literature. We also show first results from the analysis of
diffractively produced $K\bar K\pi$ states. Two prominent three-body
structures, one around $1.8\,\GeV$, the other at $2.2\,\GeV$ decaying via known
$K\bar K$ and $K\pi$ states are seen.
