When the Watch Tower Society changed its interpretation about the "superior authorities", some Jehovah's Witnesses in the USSR suspected that the change came from the KGB instead. This led to formation of the Theocratic Organisation of Jehovah's Witnesses, which discontinued use of Watch Tower Society publications printed after 1962. The group has a presence in Russia, Ukraine and Moldova, and claims to seek contacts with Witnesses in other countries. The group does not publish any statistics regarding numbers of congregations or adherents, and has little or no public presence.
