MOSCOW (AP) — Russia’s military conducted a simulated nuclear strike in a drill Wednesday 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 that revoking Russia’s 2000 ratification would “mirror†the stance of the U.S., which signed but did not ratify the nuclear test ban.
