Russia simulates nuclear strike after opting out of treaty

Drill conducted after upper house voted to rescind ratification of a global nuclear test ban

Russia's military has conducted a simulated nuclear strike in a drill overseen by President Vladimir Putin, hours after the upper house of parliament voted to rescind the country's ratification of a global nuclear test ban.

The bill to end ratification of the Comprehensive Nuclear Test Ban Treaty, approved in the lower house last week, will now be sent to Putin for final approval. Putin has said that revoking Russia's 2000 ratification would mirror" the stance of the US, which signed but did not ratify the nuclear test ban.
