Obama will march in Selma on Sunday

Barack Obama will be in Selma, Alabama this Sunday, to take part in the annual march to commemorate the voting rights marches in 1965.

Obama will speak at the Brown Chapel AME Chapel Church, and will also join Civil Rights veterans on the walk across the Edmund Pettus Bridge. Hilary Clinton will also join the march.

The Selma to Montgomery voting rights marches in 1965 drew international attention when Governor George Wallace ordered state troopers to break up the demonstrations. Troopers used sticks, whips and tear gas to disperse the crowd - all of which was captured on footage shown around the world.

The march was a major turning point for the civil rights movement, contributing to the introduction of the Voting Rights Act of 1965.
