Saudi authorities in 2018 continued to arbitrarily arrest, try, and convict peaceful dissidents. Dozens of human rights defenders and activists are serving long prison sentences for criticizing authorities or advocating political and rights reforms. Authorities systematically discriminate against women and religious minorities. In 2017, Saudi Arabia carried out 146 executions, 59 for non-violent drug crimes. A Saudi-led coalition continued an airstrike campaign against Houthi forces in Yemen that included the use of banned cluster munitions and apparently unlawful strikes that killed civilians.
