The United States on Monday will sanction more than two dozen people and entities involved in Iran's nuclear, missile and conventional arms programs, a senior U.S. official said, putting teeth behind U.N. sanctions on Tehran that Washington argues have resumed despite the opposition of allies and adversaries.
Speaking on condition of anonymity, the official said Iran could have enough fissile material for a nuclear weapon by the end of the year and that Tehran has resumed long-range missile cooperation with nuclear-armed North Korea. He did not provide detailed evidence regarding either assertion.
