TUNIS: A Tunisian police officer died in clashes with young protesters who had overturned his car during one of a series of demonstrations against mass unemployment, as unrest triggered by the death of an unsuccessful job-seeker spread to at least 11 cities around the country. Tensions have risen in the Kasserine region since Sunday when a young man was electrocuted after scaling a transmission tower to protest his rejection for a government job. Protests spread overnight into Thursday to several cities, including the capital, Tunis.
