US nuclear plans

White House officials say President Barack Obama is planning dramatic reductions in the country\'s nuclear arsenal.



Mr. Obama says this will come as part of a sweeping policy review designed to prevent the spread of atomic weapons.



According to a senior US administration official, the new strategy will point to a greater role for conventional weapons.



The official says Mr. Obama is to meet his Defence Secretary Robert Gates to discuss the new nuclear strategy.



The outcome of the discussions in a document will also set the tone for the next five-yearly review conference of the Nuclear Non-Proliferation Treaty, or NPT agreement, to be held in May.
