A historic Black church that was reportedly burnt down by Ku Klux Klan members in 1995 was ablaze late Tuesday in Greeleyville, South Carolina. This fire follows weeks of suspected arson incidents at Black churches across the U.S., and comes nearly two weeks after the June 17 mass shooting at Emanuel African Methodist Episcopal church in Charleston, South Carolina that left nine dead.

Mt. Zion African Methodist Episcopal Church is a predominantly Black church, which was among 70 suspicious fires that hit Black churches throughout the South between 1995 to 1996, according to the Chicago Tribune.

Mark Keel, chief of State Law Enforcement Division, told the Post and Courier that officials from the Bureau of Alcohol, Tobacco, Firearms and Explosives and other federal agencies were called, and an investigation is underway.

This is at least the seventh Black church to burn this month, as the conversation about #WhoIsBurningBlackChurches spreads on social media.

On Saturday, a fire destroyed College Heights Baptist Church in Elyria, Ohio. Firefighters arrived shortly after 7 a.m. and found the church fully engulfed in flames. No one was injured, Derrell Deer, the pastor of the church, told local news reporters, but what caused the fire is still under investigation.

This latest fire is one in a string of blazes set on predominantly Black churches in the U.S. Some of these fires have been deemed arson and some are under investigation as possible hate crimes.

In North Carolina, investigators determined that a fire set on June 24 at a primarily Black congregation called the Briar Creek Road Baptist Church was arson, and are asking people for any information that could help solve the case. At about the same time, a fire burned the tiny church, God's Power Church of Christ, beyond repair in Macon, Georgia. Associate pastor Jeanette Dudley got the call shortly after 5 a.m. on June 24. When the Bureau of Alcohol, Firearms and Tobacco arrived, they determined that this was arson. Investigators do not yet know if it is a hate crime.

Two other predominantly Black churches had possible arson attacks this past week, and the fire at Glover Grove Missionary Baptist Church in Warrenville, South Carolina on June 26 was not its first, according to Rev. Bobby Jones. He told the Augusta Chronicle that the church's previous building was lost in suspected arson.

The other possible arson happened on June 22 at College Hill Seventh Day Adventist in Knoxville, Tennessee. Tennessee investigators believe it was an act of vandalism and are not investigating the fire as a hate crime. Apparently at that fire, bales of hay and bags of dirt were left at the church doors.

Other suspicious blazes occurred at Black churches recently as well, according to the Atlantic:

In two other cases of fires at Southern black churches this week—at Fruitland Presbyterian Church in Gibson County, Tennessee, and the Greater Miracle Temple Apostolic Holiness Church in Tallahassee, Florida—officials suspect the blazes were caused by lightening and electrical wires, respectively, but investigations are still ongoing.

The string of arson attacks and pending investigations about how these Black churches were set on fire comes at a time of heightened racial tension in the wake of the gruesome attack that left nine people dead, including the Rev. Clementa Pinckney, a pastor and South Carolina state senator​, who President Obama recently eulogized.

Black churches have been the target of hate crimes throughout U.S. history, dating back to before the Civil War.

16th Street Church. Birmingham, Alabama - Sept. 15, 1963.

Americans learn in history class about the bombing of the 16th Street Church in Birmingham, Alabama, when Ku Klux Klan terrorists killed four girls on Sept. 15, 1963.

Mt. Zion Church. Longdale, Mississippi - June 16, 1964

On June 16, 1964, members of the Ku Klux Klan beat people leaving a church meeting in Longdale, Mississippi. They were targeting a civil rights activist named Michael Schwerner. Schwerner was not there, but the historic haven for slaves was burned down by the Klan anyway. Later, Schwerner and two other civil rights workers -- James Earl Chaney and Andrew Goodman -- drove to visit the burned church. On the way, they were pulled over, arrested, and jailed. They were released from jail then beaten and killed. Their story is told in the 1988 movie "Mississippi Burning." The case of the three murdered civil rights workers was one of the key incidents that helped finally drive national attention to the plight of Black people living in the segregated South.
