WASHINGTON (AP) — Officials say the Obama administration is moving toward decisions that would further cut the number of U.S. nuclear weapons, possibly to between 1,000 and 1,100.

The possible reductions reflect new thinking on the role of nuclear weapons in an age of terror.

President Barack Obama has said he believes the U.S. has more nuclear weapons than it needs. Cutting their numbers could save billions of dollars.

The White House has not announced any plan for reducing the number of nuclear weapons, beyond commitments made in the recently completed New Start treaty with Russia, which obliges both countries to reduce their number of deployed long-range nuclear warheads to no more than 1,550 by 2018. As of March 1, Russia had dropped its total to 1,492 and the U.S. stood at 1,737.
