Despite the absence of experimental evidence, supersymmetry remains one of the best motivated and studied Standard Model extensions. These proceedings summarise recent results from the ATLAS experiment at the LHC on inclusive searches for supersymmetric squarks and gluinos, including third generation squarks produced in the decay of gluinos. The searches involve final states containing jets and one or more leptons, and were performed with $pp$ collisions at a centre-of-mass energy of 13 TeV.
