PORT-OF-SPAIN, Trinidad (AP) _ Dominica's prime minister on Thursday urged United Nations-led military action to oust Haiti's government and return ousted President Jean-Bertrand Aristide to power.

''I have always thought that we can never have Aristide back in Haiti unless we send in an army from the U.N.,'' said Dame Eugenia Charles, who was a key backer of the U.S.-led invasion of Grenada on Oct. 25, 1983, which ended a leftist revolution.

Charles was participating in this week's summit of the 13-nation Caribbean Community. Aristide, Haiti's first democratically elected president, told the summit Tuesday that the Organization of American States should tighten the embargo it imposed on Haiti after his ouster in September.

Aristide has said he opposes military intervention to restore him.
