What are the last group of raiders to terrorize?

The last group of raiders to terrorize significant regions were often associated with various militant groups or organized crime syndicates, such as ISIS or Boko Haram, who conducted raids and attacks in the Middle East and parts of Africa. These groups have utilized guerrilla tactics, including surprise attacks and kidnappings, to instill fear and exert control over local populations. While traditional raiding has diminished, modern equivalents continue to pose threats in conflict zones.
