The United Nations human rights office expressed alarm on Friday at the significant increase in Saudi Arabia's use of capital punishment in the past year.
According to the Office of the High Commissioner for Human Rights (OHCHR), the number of executions in the country almost tripled last year compared with 2010.
"We call on the Kingdom of Saudi Arabia to respect international standards guaranteeing due process and the protection of the rights of those facing the death penalty, to progressively restrict the use of the death penalty and to reduce the number of offences for which it may be imposed," OHCHR spokesperson Rupert Colville told reporters in Geneva.
"What is even more worrying is that court proceedings often reportedly fall far short of international fair trial standards, and the use of torture as a means to obtain confessions appears to be rampant," Colville added.
Saudi Arabia applies the death penalty for a wide range of offences, including the charge of sorcery and witchcraft, for which a woman was executed last month.
