At least one person was killed in protests that turned violent in Senegal capital of Dakar Wednesday.
Police fired tear gas canisters to disperse hundreds of people who had gathered to protest a court ruling that allows the nation's elderly leader to run for another term.
Private radio station RFM said that a man was run over by the police's armored-personnel carrier. An Associated Press reporter saw the young man fall to the ground when a tank-like truck drove through the crowd.
The police launched their assault after some of the demonstrators began chanting "Palace! Palace!" indicating they planned to march on the presidential palace.
President Abdoulaye Wade, 85, is seeking his third term as president, even though the country's revised constitution imposes a two-term limit.
Wade argues that the law is not retroactive, and since he was already in office when it took effect, it should not apply to him.
Police chief Harona Sy confirmed the death of the youth, but denied that police were responsible.
"If there was the death of a man, then maybe we should talk about an accident, and we have opened an investigation," Sy said.
Senegal has historically been the most peaceful nation in West Africa. It declared its independence from France in 1960.
