Weak scale supersymmetry is one of the best motivated and studied extensions of the Standard Model. The recent increase in the center of mass energy of the Large Hadron Collider proton-proton collisions gives an opportunity to extend the sensitivity to production of supersymmetric
particles. This talk summarises recent ATLAS results on searches for supersymmetric squarks and gluinos, including third generation squarks produced directly or via decay of gluinos, with the data collected in 2015 (3.2 fb −1 ) from proton-proton collisions at a center of mass energy
of 13 TeV. The searches involve final states containing jets (possibly identified as coming from b-quarks), missing transverse momentum and leptons.
