UN High Commissioner for Human Rights Michelle Bachelet called on Venezuela to release jailed dissidents Friday and said the crisis-wracked country faced a "serious" humanitarian situation, AFP reports.

Her comments came at the end of a three-day visit to the country on the invitation of embattled President Nicolas Maduro, who has faced allegations of cracking down on political opponents amid rampant hyperinflation and shortages of basic goods.

"I call on the authorities to release all those who are detained or deprived of their liberty for exercising their civil rights in a peaceful manner," said Bachelet, referring to the hundreds of Maduro government opponents who are currently incarcerated.

"I told her that she can count on me, as president, to take her suggestions, her recommendations and her proposals seriously," Maduro said, adding that people accused of human rights abuses would be prosecuted.

Bachelet also said she had appointed delegates to remain in the country with the mandate "to provide assistance and technical advice, but also, very importantly, to continue to monitor the human rights situation across Venezuela."
