I study the Ds(2317) and Ds(2457) discovered at BABAR, CLEO and BELLE, and find that they belong to a class of strange S=-1 tetraquarks and pentaquarks, which is equivalent to the class of kaonic molecules bound by short range attraction. In this class of hadrons a kaon is strongly trapped by a s-wave meson or baryon. To describe this class of multiquarks the Resonating Group Method is applied to a standard quark model with chiral symmetry breaking, and the short range kaon-meson(baryon) interactions are extracted. A criterion is derived to classify the attractive channels. I conclude that the mesons Bs(0+), Bs(1+), and the baryons Omega cc, Omega cb, Omega bb clearly belong to the new hadronic class of the Ds(2317) and Ds(2457). The hadrons f0(980), Lambda, Sigma c, Sigma b possibly belong to a related family.
