One person was killed and 24 injured when inmates set mattresses on fire during an attempted jailbreak in the central Tunisian city of Kasserine, authorities said Tuesday. One inmate was killed and 24 others overcome by smoke fumes, an government official said. TAP news agency said relatives of the inmates gathered outside the jail in search of news and stoned troops who had surrounded the building. In late April, several prisoners escaped from the same facility after setting fire to one of their cells.
