Capt. Amadou Sanogo was to be installed as the new president Wednesday. His supporters called for the immediate resignation of Dioncounda Traore, who was beaten and rushed to a hospital with head injuries after hundreds of protesters stormed the presidential palace Monday. "The people want Sanogo to come back for the transition of power," said El Hadj Bamba Mohammed, spokesman for one of the groups backing Sanogo. However, the Economic Community of West African States (ECOWAS), which has tried to broker a return to civilian rule after the March 22 coup, decided to let Traore remain in charge for a year to oversee a transition back to democracy. Over the weekend, Sanogo agreed to abide by the decision. But his supporters stood defiantly against the regional bloc. Mali experienced two decades of democratic rule and was hailed as an example of African stability. But it plunged into chaos in the aftermath of the coup that ousted President Amadou Toumani Toure from power. Separatist rebels capitalized on the trouble in Bamako and took over chunks of territory in the north. Islamists now control two-thirds of the country. Protesters said Traore, a former parliamentary speaker, was part a self-serving political elite that has misruled the country for years. "People have no faith in the politicians to organize elections and resolve the situation in the north," said Youssouf Kone, leader of several groups demanding the president's resignation. "That's why they want Sanogo to return to power in the role of president," Kone said.
