A prominent opposition figure in Tunisia, Mohamed Brahmi, has been shot dead in the capital Tunis.
The founder and one-time leader of the nationalist and secular Popular Party was a
forceful critic of the Islamist-led government.
The 58-year-old was gunned down outside his house in Tunis in front of his disabled daughter, according to a party member. The killers then escaped.
No-one has claimed responsibility. The Islamist ruling party Ennahda has condemned the killing.
Even so, reports say protesters reacted to the murder by setting fire to Ennahda’s headquarters in the central city of Sidi Bouzid.
Mohamed Brahmi was a member of the Constituent Assembly charged with drawing up a new Tunisian constitution.
Last February saw the murder of another secular politician, Chokri Belaid, which police said was probably carried out by a radical Salafist group.
That killing sparked the worst violence in Tunisia since the fall of the dictator Ben Ali in 2011.
