The US Senate ratified on Thursday a treaty to cut US and Russian long-range nuclear warheads by two-thirds.
The treaty, signed by US President George W. Bush and Russian President Vladimir Putin in Moscow last year, would reduce Russia's and America's deployed nuclear arsenals to between 1,700 and 2,200 warheads, from about 6,000 each.
The Senate approves the treaty by vote of 95-0. A two-thirds majority was needed for approval.
