U.S. Says Russia Defying Test Ban Treaty

“Russia has likely been secretly carrying out very low-yield nuclear tests to upgrade its nuclear arsenal, according to a new U.S. intelligence assessment, challenging Moscow’s claims that it is faithfully adhering to an international treaty banning nuclear tests,” the Wall Street Journal reports.

“The assessment marks the first time the U.S. has said the Kremlin has failed to strictly observe its commitments under the Comprehensive Nuclear Test Ban Treaty.”
