Ukraine slaps sanctions on Russia's Yandex, other web businesses

Ukraine has imposed sanctions on Russia's largest internet group Yandex and other popular web businesses including the operator of social media sites Vkontakte and Odnoklassniki, the president's office said on Tuesday.

The decree by Ukrainian President Petro Poroshenko also banned Ukrainian web hosts from linking to the Russian websites from May 15.

The restrictions added to an existing list of more than 400 Russian individuals and companies sanctioned by Kiev following Russia's annexation of Crimea in 2014 and the ensuing pro-Russian separatist uprising.
