The Associated Press reports from DAKAR, Senegal — Police arrested two prominent rappers and opened fire with tear gas on protesters who had gone ahead with a banned demonstration Thursday.

The sleep-in protest was organized by a group of rappers known as Y'en a Marre, French for "We've had enough," which is allied with the opposition but is not fielding a candidate in the election. Riot police began pelting the group with tear gas, after protesters tried to light tires on fire.

Security forces moved in and arrested Simon and Kilifeu, two of the founders of the Y'en a Marre, who were led away to a police truck.
