Which countries currently have nuclear weapons?
Nine countries currently either say they have nuclear weapons or are believed to possess them.
The first to have nuclear arms were the five original nuclear weapons states — the United States, Russia, China, France and the United Kingdom.
All five are signatories to the Nuclear Nonproliferation Treaty, which commits countries that don't have nuclear arms not to build or obtain them, and those that do to 'pursue negotiations in good faith' aimed at nuclear disarmament.
