00:00Russia says it is no longer bound by limits on deployed nuclear warheads
00:05after the last remaining nuclear arms control treaty with the United States expired.
00:11The new START agreement, signed in 2010,
00:14placed limits on the number of strategic nuclear weapons both countries could deploy.
00:19The treaty formally ended on Thursday.
00:24Russia's foreign ministry says Moscow will continue to act responsibly
00:28but warn it is ready to take countermeasures if its security is threatened.
00:33The treaty capped each side at 1,550 deployed strategic warheads
00:38and created rules for inspections and transparency between the two nuclear powers.
00:44In September, Russian President Vladimir Putin proposed to extend the limit for another year.
00:49Moscow says that Washington did not give a formal response to the offer.
00:54At the same time, US President Donald Trump called the proposal reasonable
00:57but no negotiations followed.
01:00Despite the treaty ending, the Kremlin said it remains open to future arms control talks with the United States.
