Israeli Foreign Minister Tzipi Livni has sharply criticized Iran's leaders and accused them of pursuing weapons to destroy her country.
In her address before the United Nations General Assembly Wednesday, Livni said "there is no greater challenge to our values than that posed by the leaders of Iran."
She called on the international community to stand up against Iran.
Earlier, Afghanistan's President Hamid Karzai told the Assembly that his country's future is threatened by foreign terrorists from abroad -- a clear reference to neighboring Pakistan.
Pakistan's President Pervez Musharraf later strongly rejected the Afghan leader's suggestion that his country was not doing enough to stop terrorism. He told reporters that Afghan military forces must do more to fight terrorism.
Also Wednesday, Venezuelan President Hugo Chavez and Cuban Vice President Esteban Lazo Hernandez separately criticized the United States in their addresses before the General Assembly.
Mr. Hernandez said President Bush has increased what he called the "brutally hostile" embargo against Cuba.
Mr. Chavez repeatedly called President Bush a "devil" during his address. The Venezuelan president urged world leaders to resist what he called American imperialism.
Mr. Chavez accused the United States of seeking to control the world and exploit its resources, and renewed calls for U.N. reform to reduce what he called U.S. influence.
The U.S. ambassador to the United Nations, John Bolton, said it is President Chavez who is attempting to influence other countries. Bolton said rhetoric like that by Mr. Chavez is counterproductive to Venezuela's interests.
