Sources such as "The Weiser Field Guide to the Paranormal" claim that she foretold the break-up of the Soviet Union, the Chernobyl disaster, the date of Stalin's death, the sinking of the Russian submarine "Kursk", the September 11 attacks, Topalov's victory in the world chess tournament, the tensions with North Korea. On the other hand, Bulgarian sources say that the people who were close to her claim that she never prophesied about "Kursk", World War III, circulating on the Internet, and that many of the myths about Vanga are simply not true. Some evidence has also been presented that Baba Vanga did not make many of the predictions now attributed to her, but rather people frequently attribute new fake "prophecies" to her since her death, and the lack of a written record of her prophecies, makes any prediction attributed to her difficult to disprove.
