Deep concern over violence in VenezuelaListen /
The UN says it's "deeply concerned" about the escalation of violence and the death of at least three people during demonstrations in the Venezuelan capital, Caracas.
The government's Public Prosecutor added that, 66 people were wounded and 69 detained.
Thousands of people in cities throughout Venezuela reportedly participated in protests against the detention of student demonstrators earlier in the week.
They are also protesting against rising crime rates and increasing economic hardship in the country.
Rupert Colville from the UN human rights office, OHCHR, said basic human rights should be upheld by the government.
"The Regional Representative of the High Commissioner for Human Rights in South America has called on the Government of Venezuela to ensure that the rights to freedom of peaceful assembly and freedom of opinion and expression are guaranteed, and that a prompt, full and impartial investigation into the killings and any act of excessive use of force is undertaken."
OHCHR has called for all detainees to be promptly brought before justice.
And it has urged all parties in Venezuela to engage in peaceful dialogue to find a way through this crisis.
