A demonstrator holds a tear gas rocket and its shell during a protest to demand the resignation of the country's interim prime minister, who was part of the regime of ousted president Zine El Abidine Ben Ali, on February 26, 2011 in Tunis. Security forces fired warning shots and tear gas, and protesters responded by hurling stones as clashes erupted during a demonstration in the Tunisian capital, AFP reporters said. In response to growing protests, Prime Minister Mohamed Ghannouchi's government announced Friday that it will hold elections by mid-July.
