The annual United Nations General Assembly debate continues today with Venezuelan President Hugo Chavez and the head of the Cuban delegation among the leaders addressing the world body.
Venezuela and Cuba are close allies and have declared support for Iran's peaceful use of nuclear technology - a key issue being confronted by the assembly.
The Bush administration has labeled Mr. Chavez a destabilizing factor in Latin America, and accuses Iranian President Mahmoud Ahmadinejad of trying to develop nuclear weapons.
President Bush and Mr. Ahmadinejad clashed over Iran's nuclear ambitions in addresses to the U.N. Tuesday, but Washington agreed to allow more time for talks with Tehran.
Other leaders scheduled to address the assembly today include the heads of state of Afghanistan, Panama, Togo, Chile, Sri Lanka, Nigeria, Maldives and Italy.
