The first Fermi Large Area Telescope (LAT) catalogue of sources (1FHL)\nemitting at high energies (above 10 GeV) reports the details of 514 objects\ndetected in the first three years of the Fermi mission. Of these, 71 were\nreported as unidentified in the 1FHL catalogue, although six are likely to be\nassociated with a supernova remnant (SNR), a Pulsar Wind Nebula (PWN) or a\ncombination of both, thereby leaving a list of 65 still unassociated objects.\nHerein, we report a preliminary analysis on this sample of objects\nconcentrating on nine 1FHL sources, which were found to have a clear optical\nextragalactic classification. They are all blazar, eight BL Lac and one flat\nspectrum radio quasar, typically at redshift greater than 0.1.\n
