Cuba's foreign minister warned that while the Cold War is long over, the threat of nuclear war still looms if Iran is attacked over its nuclear program.
The U.S. accuses Iran of hiding plans to build a nuclear bomb; Iran denies that and says it's working only toward building nuclear power plants.
Iranian President Mahmoud Ahmadinejad told The Associated Press on Sunday that international nuclear regulators had never found proof that Iran is pursuing an atomic bomb.
"Today the same firm voice of our historical leader is in front of an international call for peace, and cautioning about the risk that a military attack against Iran would have for the world, putting it on the brink of a nuclear war," foreign minister Bruno Rodriguez said.
Rodriguez spoke Sunday in Harlem, at an event commemorating the September 1960 encounter between Cuban President Fidel Castro and the black civil rights leader Malcolm X.
Castro, visiting New York City then to attend the United Nations General Assembly, stayed at the Hotel Theresa in Harlem.
Rodriguez said 50 years after Malcolm X met with Castro in the midst of the Cold War, the Cuban people still rely on the support of African-Americans, Cuba's foreign minister said.
Rodriguez said the first Communist Cuban delegation to the United Nations received support from Malcolm X and other black leaders and forged a lasting bond between "Cuban revolutionaries and the African-American progressive people."
Also at the event, a panel of Cuban supporters asked for help freeing five Cubans imprisoned for espionage in the United States. They also remembered the legacy of the Rev. Lucius Walker, who directed a program to send Americans to study medicine in Cuba.
