Rev. Al Shaprton and other elected officials led a day of remembrance in honor of the victims of this week’s Black church massacre that occurred in South Carolina.

The event took place at Sharpton’s weekly rally at the National Action Network (NAN) headquarters in Harlem on Saturday morning

Nine Black church members at the Emanuel AME Church in Charleston, S.C. were killed by white gunman Dylann Roof on Wednesday. Roof confessed to the killing and is being held on $1 million bond. He is charged with nine counts of murder and firearm possession.

Sharpton traveled to Charleston on Thursday and visited the Emanuel AME Church to pay tribute to those slain, including the leader of the church, 41-year-old Rev. Clementa Pinckney whom NAN worked with.

“The question becomes now whether he acted alone, what is involved and how people are further protected. This is by far one of the most horrific acts that I’ve ever seen,” Sharpton said this week. “To walk into a church and kill nine people in a place that should be safe; a new low in hate and atrocities in this country. None of us are safe if we cannot go to a church for bible study.”
