  The NA61/SHINE strong interaction programme aims to explore the phase diagram
of the strongly interacting matter. The main physics goals are the study of the
onset of deconfinement and the search for the critical point of the strongly
interacting matter. These goals are pursued by performing a scan in beam
momentum (13A -- 158A GeV/c) and size of colliding system (p+p, p+Pb, Be+Be,
Ar+Sc, Xe+La, Pb+Pb). This contribution presents new results on system size and
energy dependence of multiplicity and net-charge fluctuations measured with
higher-order moments of these distributions. Also, new results on the
measurement of Bose-Einstein correlations in nucleus-nucleus collisions based
on Levy sources are discussed as well as news on anisotropic flow in Pb+Pb
interactions at 13A GeV/c.
