Results of new measurements of diffractive cross sections in deep-inelastic
scattering (DIS) and photo-production at HERA are presented. The cross sections
of dijet and open charm production are compared with next-to-leading order (NLO)
QCD predictions based on parton distribution functions obtained from diffractive
inclusive DIS data. A combined NLO QCD fit to the inclusive and dijet DIS data
is performed to determine diffractive quark singlet and gluon densities with a
better precision. Recent measurements of elastic vector meson production and
deeply virtual Compton scattering at HERA are also reviewed.
