US President Obama has delivered the eulogy at the service for the church leader and South Carolina state senator, Clementa Pinckney, who was among nine people shot dead in the city of Charleston last week.

The attack on the bible study group at a historic African-American church is thought to be racially motivated.

President Obama concluded his oration by leading the congregation in singing the hymn, Amazing Grace.
