WASHINGTON (AP) -- Defense Secretary Robert Gates says this week's nuclear security conference represents the first real concerted international effort to confront the threat of nuclear material falling into the hands of terrorists.
Gates says that until now, the threat has mostly been one that people talk about, but have few means to address.
Gates says the conference offers a way to reinforce existing global controls on nuclear materials and look for new ways to secure the world's stockpiles of nuclear raw materials.
U.S. officials estimate that stockpile at roughly 1,600 tons of highly enriched uranium and 500 tons of plutonium. That could be enough to build well over 120,000 nuclear weapons.
WASHINGTON (AP) -- The White House says Ukraine is announcing it will get rid of its stockpile of highly enriched uranium, enough to build several nuclear weapons, by 2012.
Robert Gibbs, spokesman for President Barack Obama, made the announcement in a briefing shortly before the U.S. leader was to open a nuclear nonproliferation conference attended by the leaders of 47 countries.
Gibbs said the Ukrainian decision marks the conclusion of several years of effort by the United States on that front. Obama had just finished a meeting with new Ukrainian President Viktor Yanukovich when the announcement was made.
