Tunisia rocked by several protests

Beji Caid Essebsi, the Tunisian prime minister, has said that a new outbreak of deadly violence in Tunisia is designed to prevent the country holding its first post-revolution elections.

"There were disturbances aimed at preventing elections," said Essebsi during an address to the nation on Monday. "These elections will be held on October 23 as scheduled."
