 Beji Caid-Essebsi will replace Mohammed Ghannouchi, who resigned earlier Sunday after becoming a major irritant to Tunisians behind the so-called "Jasmine Revolution" that toppled autocratic President Zine El Abidine Ben Ali last month and sparked a wave of upheaval in the Arab world. The fall of Mr Ben Ali after 23 years in power sparked similar uprisings in the Arab world, including one that led to the downfall of long-time Egyptian President Hosni Mubarak on 11 February and another under way in Libya. Earlier in the day, police in Tunis fired tear gas and warning shots to disperse the latest demonstration calling for a new government and a new constitution on a third day of violence.
– Interim Tunisian President Foued Mebazaa has appointed a new prime minister following the resignation of Mohammed Ghannouchi, who bowed to protesters' demands and stepped down yesterday, the BBC reports. Former foreign minister Beji Caid-Essebsi will take Ghannouchi's place, although it's not clear whether the appointment will be enough to mollify the protesters who have returned to the streets of Tunis in large numbers, AP notes. Osama bin Laden's deputy Ayman al-Zawahri has recorded a message urging Tunisians and Egyptians to rise up against their interim governments.
