"Human rights are under assault," said the secretary-general as he opened the UN Human Rights Council's main annual session in Geneva."People are being left behind. Fears are growing," he said, pointing to swelling divisions and political polarisation in many countries."A perverse political arithmetic has taken hold: divide people to multiply votes," he said, warning that "the rule of law is being eroded".Guterres said civilians were being "trapped in war-torn enclaves, starved and bombarded in clear violation of international law" as well as "human trafficking, affecting every region in the world, preying on vulnerability and despair".READ | Libya's warring rivals resume talks in Geneva - UNHe also said women and girls were being "enslaved, exploited and abused", "activists tossed in jail, and religious and ethnic minorities groups persecuted".
