  The exploration of the QCD phase diagram is the most important task of
present heavy ion experiments. In particular, we want to study the phase
transition from hadronic to partonic matter and look for the critical point
(CP) of strongly interacting matter. Fluctuations and correlations in kinematic
characteristics and particle yields may help to locate the CP (in analogy to
enlarged fluctuations due to critical opalescence close to a CP in a liquid/gas
transition). The strong interactions program of the NA61/SHINE experiment may
allow to discover or rule out the existence of the CP in the Super Proton
Synchrotron energy domain. For this purpose we perform a two-dimensional scan
by varying the energy ($5.1 < \sqrt{s_{NN}} < 16.8/17.3$ GeV) and the system
size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb) of the collisions.
  In this report new NA61/SHINE results on fluctuations and correlations in
p+p, Be+Be, and Ar+Sc collisions are presented. In particular, results on
transverse momentum and multiplicity fluctuations, as well as higher order
moments of net-charge fluctuations are discussed. The NA61/SHINE data are
compared to predictions of string hadronic models and to NA49 results.
