Members of the country's opposition movement said they will keep up their protests to try to force Wade to withdraw, Voice of America reported Saturday.
Demonstrators are angry that Wade is seeking a third term after he amended the country's constitution to include a two-term limit in 2001.
Even though he pledged in 2007 he wouldn't run again, Wade now said he needs a third term to complete several initiatives, Voice of America said.
Presidential candidate Ibrahima Fall has called for a delay in the elections because of recent unrest. At least 10 people died in protests since the nation's Constitutional Council approved the president's candidacy Jan. 27.
The Constitutional Council also oversees the elections, which opposition leaders say brings its independence into question. Observers from the European Union, the African Union and the Economic Community of West African States will monitor voting.
