HAVANA (Reuters) - Havana on Thursday demanded justice for the victims of the 1976 bombing of a Cuban plane and accused Washington of "double standards" in the fight against terrorism because of its alleged complicity with people responsible for attacking the island nation.

A special session of Cuba's National Assembly, held during a week of events to mark the 25th anniversary of the attack, honored the 73 people who died on Oct. 6, 1976, when two bombs went off in the Cuban passenger plane near Barbados.

"We will continue denouncing their murderers and asking for punishment," said a declaration approved by the assembly.

Cuba blames the attack on two Cuban Americans -- Orlando Bosch, who has been living in Florida for more than a decade, and Luis Posada Carriles, jailed in Panama since November 2000 after an alleged attempt to kill Cuban President Fidel Castro.

Taking advantage of the worldwide focus on terrorism in the wake of the Sept. 11 attacks on the United States, Cuba has intensified demands to have the pair brought to justice.

"We have the moral strength to demand for justice to be done ... to ask for the international effort against terrorism to be sincere, consistent, without double standards, without hegemonic powers," the declaration added, in reference to the campaign launched by Washington after the Sept. 11 attacks to fight terrorism around the globe.

CUBA OPPOSES MILITARY ACTION

Havana says that Bosch is still planning attacks against Cuba from Florida with "total impunity" and that the 1976 attack illustrates the kind of terrorism it has faced since Castro's 1959 revolution without U.S. or U.N. condemnation.

"Thousands of Cubans have lost their lives or suffered damages as a consequence of attacks by groups which have operated and still do from United States soil, where they have had the complicity or tolerance of the authorities," the document said.

Cuba has condemned the recent attacks on New York and Washington, but is opposed to any military action against Saudi-born dissident Osama bin Laden, accused of masterminding the attacks, or the Taliban rulers, who are sheltering him in Afghanistan.

The pro-government Cuban parliament also unanimously ratified another nine international anti-terrorism pacts, so that Havana has now signed up to all 12 anti-terrorism agreements following a call from the United Nations this week.

Cuba is on the State Department's list of states that allegedly sponsor terrorism. Havana in turn accuses Washington of 42 years of aggression against the communist-run island via an economic embargo and support for violence against the Castro government such as the 1976 incident.

Throughout the week, Cuban state media have been featuring interviews with relatives of the victims of the 1976 bombing. The ruling Communist Party is planning a mass rally in Havana's Revolution Square on Saturday's anniversary.
