Russia is revoking ratification of nuclear test ban treaty: Parliament speaker

Russia is withdrawing its ratification of the Comprehensive Nuclear Test Ban Treaty due to the United States' irresponsible approach to global security, according to the speaker of the Russian parliament. President Vladimir Putin had previously suggested revoking ratification because the US had not ratified the treaty. Russia will remain a signatory and will continue to cooperate with the test ban treaty organization and the global monitoring system.
