TUNIS: Clashes erupted for a second night on Saturday between police and youths in the central Tunisian city of Kairouan after a man died following a police chase, according to his family, fueling authorities’ fears that protests could spread across the country. As Tunisia prepares to mark the January anniversary of the 2011 revolution, which sparked the Arab Spring uprising, tensions have risen amid protests, and a powerful UGTT union call for a nationwide strike next month.
