In addition to condemning the assassination attempt on Argentina Vice President Cristina Fernández de Kirchner's life, the United Nations High Commissioner for Human Rights also called for clarification of all the elements surrounding the attempt, as well as a return to calm through dialogue.

"We are shocked and it is crucial that an investigation into what and how things happened is carried out," said Ravina Shamdasani, spokesperson for the UN.

On Thursday, Sept. 1 in Buenos Aires, capital of the country, a man was arrested after attempting to shoot at Kirchner from point-blank range in the vicinity of her home. It happened as a vigil was being held by supporters.

"Any type of political violence is condemnable and it is important that differences are resolved through dialogue," the spokeswoman added.

Argentina is currently experiencing a period of major political tension and the vice president is facing a request for jail in the framework of an oral trial against her for alleged corruption in the awarding of public works during her presidential administration, from 2007-2015.
