Washington: In the two weeks after a racially motivated massacre claimed lives of nine African-Americans, at least six predominantly African-American churches in south US had been burnt down, Xinhua news agency reported on Wednesday.

The latest fire occurred on Tuesday night in the Mount Zion Church in Greeleyville, South Carolina, 20 years after it was set ablaze by the white supremacist group Ku Klux Klan. The fire left the church roofless and given lightning and storms were reported overnight in the region, authorities said it was still too early to determine the cause of the fire.
