Iran could reach key point for nuclear bomb by mid-2014: U.S. experts

WASHINGTON (Reuters) - Iran could produce enough weapon-grade uranium for one or more nuclear bombs by mid-2014, and the United States and its allies should intensify sanctions on Tehran before that point is reached, a report by a group of U.S. nonproliferation experts said.

President Barack Obama should also clearly state that the United States will take military action to prevent Iran from acquiring a nuclear weapon, the report said.
