We present a list of 24 new blazar candidates selected in a search for possible counterparts of spatial clusters of gamma-ray photons in the recent 9Y-MST catalogue, at energies higher than 10 GeV and at Galactic latitudes higher than 20 degrees. 13 of these clusters are also included the preliminary release of the 4FGL catalogue of gamma-ray sources. The search for possible counterparts is based on the possible associations of the clusters with radio sources within a circle having a radius of 6 arcmin. We then investigated the possible optical or mid-IR associations of these sources, checking if they show some properties typical of new blazar candidates.
