Tunis Thousands of protesters gathered in Sidi Bouzid, cradle of the Arab Spring uprisings, after a prominent secular opponent of Tunisia's moderate Islamist-led government was shot dead on Wednesday.
"More than four thousand are protesting now, burning tires and throwing stones at the police," Mehdi Horchani, a Sidi Bouzid resident, told Reuters. "There is great anger".
Thousands were also protesting in Tunis after Shokri Belaid was killed outside his home there on Wednesday.
Tunisians rose up against long-time leader Zine al-Abidine Ben Ali after vegetable seller Mohamed Bouazizi set fire to himself in Sidi Bouzid in late 2010.
