An alleged coup d'état attempt occurred in Madagascar on November 18, 2006, during the lead-up to the December 3 presidential election, when retired army General Andrianafidisoa, also known as Fidy (and a previous Director General of OMNIS), declared military rule.

[1][2] According to judicial authorities, Andrianafidisoa was not allowed to run for president after failing to pay a 25 million ariary (US$11,400) deposit.

[2] General Fidy declared military rule and set up a base near the Ivato Airport in the capital, Antananarivo.

[3] In a radio interview on November 20, Fidy, who had still not been captured, said that the idea that there had been a coup attempt was a misinterpretation, but acknowledged that he had called for Ravalomanana's resignation because he considered the government to be unconstitutional.

[2] On November 22, Fidy received the backing of most of the 14 presidential candidates, who said he was defending the constitution and the interests of the nation.
