Riots and violent clashes between Tunisian police and protesters broke out on Sunday in the capital Tunis and several other cities for the second consecutive day, with a security spokesperson saying riot police had arrested 242 people, mostly teenagers and children who vandalised property and tried to rob shops and banks. Al Jazeera reports that the protesters made no clear demands in demonstrations – which authorities described as riots – in at least 10 cities around the country but the protests do pose a challenge for the government of Hicham Mechichi, who has reshuffled his cabinet amid a continuing battle for political influence.
