Japan's chief government spokesman has said the nation will put cyberattack countermeasures in place to make sure the Tokyo Olympics are a success.

The U.K. and the United States on Monday condemned what they said were a series of malicious cyberattacks orchestrated by Russian military intelligence, including attempts to disrupt the Tokyo Olympics and Paralympics. The Games were originally set for this year but were postponed due to the novel coronavirus pandemic.

Chief Cabinet Secretary Katsunobu Kato told a news conference Tuesday that Japan was in close contact with London and Washington over the issue and was gathering and analyzing information, but did not give further details.
