The Security Services of Ukraine (SBU) raided the offices of Russian tech company Yandex in UKranian cities Kiev and Odessa today.
"There are representatives of the Ukrainian Security Services in our Kiev and Odessa offices," a company representative told the TASS news agency. "We do not have information about why they are there."
A SBU spokesperson said Yandex was being investigated for “treason.”
The raids come after Yandex and other Russian websites were blocked in Ukraine May 16. Yandex and Russian social media sites VKontakte and Odnoklassniki were blocked under the orders signed by Ukrainian President Petro Poroshenko.
In addition to search engines and social media, Ukraine has blocked Russian television channels and online services including Mail.ru. Millions of Ukrainians use the web services.
