The Russian Foreign Ministry on Friday warned the US not to resume full-scale nuclear tests after President Vladimir Putin withdrew Moscow's ratification of the Comprehensive Test Ban Treaty (CTBT) in order to restore parity.

"The United States must understand that conducting full-scale tests, for which the infrastructure in Nevada is reportedly prepared, will force us to respond in kind," the ministry said in a statement.

Last month, the US Department of Energy's National Nuclear Security Administration (NNSA) carried out an underground detonation at a site northwest of Las Vegas with the purpose of "improving the detection of underground nuclear explosive tests." The explosion involved "chemical high-explosives and radiotracers," the NNSA said.
