The United Nations says at least 219 people died during the protests which toppled Tunisia's President Zine al-Abidine Ben Ali last month. UN team leader Bacre Waly Ndiaye said this figure included 72 people who died during prison riots. Mr Ndiaye was speaking at the end of a week-long human rights team investigation into the unrest. He added that the figure was not final and the UN would continue its investigations. The government has previously said that 78 people had died, although the opposition said the figure was higher. The former Tunisian leader Mr Ben Ali has fled to Saudi Arabia. A unity government has been sworn in but some protests continue, from people who want anyone linked to the former regime to leave power.
