MOSCOW (Reuters) - Russia's top search site Yandex (>> Yandex NV) said on Tuesday it did not expect Ukraine sanctions to have a material negative impact on its consolidated results.

Ukraine is a small part of the company's business, Yandex said in a statement, adding it regretted the country's decision to deny access to its resources to Ukrainian citizens and organisations.

Ukraine imposed sanctions on Russia's largest internet groups including Yandex and Mail.ru (>> Mail Ru Group Ltd) on Tuesday, saying it wanted to guard against cyber attacks.

Yandex said 11 million Ukrainian users used its services every month.
