Yandex banned Google?

Yandex reset TIC for google.com and google.ru domains. The link "Google" - a search engine "from Yandex.Catalog now leads to a porn site.

search.yaca.yandex.ru/yca/cy/ch/google.ru

What is happening?

UPD Answer of the representative of Yandex:

We respect our competitors and, of course, they did not declare war on anyone. The thing is that an error crept into the mirror gluing algorithm, as a result of which the google.com and google.ru domains were grouped with this site. The error has already been eliminated, justice has been restored. Thank you for your vigilance :)
