UNITED NATIONS (Reuters) - Israeli Prime Minister Benjamin Netanyahu drew his "red line" for Iran's nuclear program on Thursday despite a U.S. refusal to set an ultimatum, saying Tehran will be on the brink of a nuclear weapon in less than a year.

By citing a time frame in an address to the U.N. General Assembly, Netanyahu - who has clashed with President Barack Obama over the urgency of military action against Iran - appeared to suggest no Israeli attack was imminent before the November 6 U.S. presidential election.
