NCA Deputy Director General Phil Gormley said: “This is the first time the UK has had the capability to coordinate a single targeted operation of this nature.
"Over the past six months we have seen unprecedented levels of cooperation to deliver this result.
“Our aim was to protect children who were victims of, or might be at risk of, sexual exploitation.
"A child is victimised not only when they are abused and an image is taken. They are re-victimised every time that image is viewed by someone.
