PORT-AU-PRINCE, Jan 16 (Reuters) - Exiled former Haitian dictator Jean-Claude Duvalier returned unexpectedly to his Caribbean homeland on Sunday for the first time since he was deposed in a coup in 1986.

Duvalier, known as “Baby Doc,” who had ruled Haiti following the 1971 death of his father, the authoritarian Francois “Papa Doc” Duvalier, had been living in France in exile.

Enthusiastic supporters greeted him at the airport, but it was not immediately clear why he had returned. (Reporting by Joseph Guyler Delva: Editing by Pascal Fletcher and Peter Cooney)
