The church where nine black worshippers were shot dead in South Carolina on Wednesday will re-open for Sunday prayers today.
Meanwhile, demonstrators have been protesting outside the South Carolina Capitol Building calling for the state to take down the Confederate flag.
It comes after photographs emerged showing the suspected Charleston church shooter burning the Stars and Stripes flag, along with a racist manifesto.
The images also show 21-year-old Dylann Roof posing with weapons and holding a Confederate flag.
In the four-page manifesto, Roof suggests he had "no choice" but to act on his concerns about ethnic groups in the US.
"I chose Charleston because it is the most historic city in my state, and at one time, had the highest ratio of blacks to whites in the country," he wrote.
"We have no skinheads, no real KKK, no one doing anything but talking on the internet. Well someone has to have the bravery to take it to the real world, and I guess that has to be me."
The Confederate flag, which is regarded by some as a symbol of racism, still flies outside South Carolina's state legislature, where several thousand protesters gathered on Saturday.
Waving placards and singing "We Shall Overcome", they demanded the flag be taken down following the Charleston shootings.
President Barack Obama has said he believes it now belongs in a museum - a sentiment echoed by one-time Republican nominee Mitt Romney.
He tweeted:
Take down the #ConfederateFlag at the SC Capitol. To many, it is a symbol of racial hatred. Remove it now to honor #Charleston victims.

Mr Obama has also renewed his call for stricter gun laws, saying he blamed public apathy combined with the tight "grip" of the National Rifle Association on Congress for preventing change.
"Unfortunately, the grip of the NRA on Congress is extremely strong," he said in an interview recorded on Friday, two days after the massacre at The Emanuel African Methodist Episcopal Church.
Funeral plans have been announced for one of the shooting victims, South Carolina state Senator Clementa Pinckney.
Her casket will be taken to the Statehouse for public viewing on Wednesday afternoon, with additional viewings on Thursday at a Columbia church and the church where she died.
The funeral will be held at 11am on Friday at TD Arena on the College of Charleston campus.
According to Roof's friends, he had drunkenly claimed he was "going to hurt a bunch of people" at a college in Charleston seven days before the church attack.
Christon Scriven, who is black, said he was so concerned by the outburst that he hid Roof's 45-calibre handgun in the air-conditioning vent of a mobile home.
He was given back his weapon days before the fatal shooting, after a girl living in the trailer said she did not want it there.
"I think he couldn't get into the school because of the security… so I think he just settled for the church," Mr Scriven, 22, told reporters.
In a vivid account, he described Roof as an extremely unhappy person who drank heavily and flitted between the homes of his divorced parents because he felt unloved.
On Friday, Roof appeared in court via video link, handcuffed and dressed in a jail jumpsuit. He spoke only to answer questions, stating his age and that he was unemployed.
He is charged with nine counts of murder and possession of a firearm in connection with the shooting spree in Charleston. All of the victims were African-American. He remains in custody.
