Human Rights chief condemns killing of Tunisian politicianListen /
UN Human Rights High Commissioner Navi Pillay is calling on the Tunisian authorities to investigate the assassination of a politician who was a staunch opponent of political violence.
Opposition leader Chokri Belaid was shot as he was leaving his home in the capital, Tunis, on Wednesday morning.
Cécile Pouilly, spokesperson with the UN Human Rights Office in Geneva, says Belaid was a great defender of human rights and democratic values.
"What we see is really an environment of increasing political violence and the latest killing really is an additional threat to the democratic transition that is happening now in Tunisia following the revolution, and therefore we are very worried about this increasing political violence" (19 secs)
The UN Human Rights Office says it has received reports from Tunisia of people who, like the late politician, have received death threats.
It calls on the country's authorities to act "very seriously and very quickly" to investigate the killing and to provide better protection for those who have been threatened.
