The United Nations' top human rights body on Thursday decided by a comfortable margin to establish a new investigative mission to probe Iran's suppression of mass protests that have roiled the country since September.
The motion passed with 25 in favor, six against and 16 abstentions. Activists cheered after the result was read out by the council president and some diplomats applauded.
Tehran's representative at the Geneva meeting Khadijeh Karimi earlier accused Western states of using the rights council to target Iran, a move she called "appalling and disgraceful".
