The United Nations' top human rights official has scheduled a trip to Venezuela next week featuring meetings with President Nicolás Maduro and opposition leader Juan Guaidó, among others.

U.N. High Commissioner for Human Rights Michelle Bachelet's office said the former Chilean president will visit Venezuela from June 19-21. It said Friday that she will hold discussions with government officials, the head of the supreme court and the attorney general, the president of the National Assembly — a job held by Guaidó — and the head of the government-backed Constituent Assembly.

Bachelet's office said she also will "engage with victims of human rights violations and abuses and with their relatives," without giving further details.

Guaidó has been unable to weaken Maduro's grip on power and sway the powerful military.
