United Nations International Day in Support of Victims of Torture: Date and History

The UN International Day in Support of Victims of Torture is observed on June 26th to commemorate the day in 1987 when the UN Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment came into force.
This convention is a crucial instrument in the global fight against torture.
The prohibition of torture is considered a part of customary international law, which means that it is legally binding on all countries, regardless of whether they have ratified specific treaties that explicitly prohibit torture.
The official website highlights that the systematic or widespread practice of torture is recognized as a crime against humanity.
