Latvia's government on March 16 issued a reminder that four years on from Russia's illegal annexation of Ukraine's Crimea region, nothing has changed as fr as recognition of the aggression is concerned.
Residents of Crimea, which rejoined Russia in 2014, cast their ballots in the Russian presidential election for the first time.
Kyiv is also angry with Russia's support for separatists in eastern Ukraine, where more than 10,300 people have been killed in fighting since April 2014.
"On Sunday, March 18, 2018 security arrangements for Russia's Ukraine-based diplomatic missions in Kiev, Kharkiv, Odessa and Lviv will not provide access to these facilities for Russian nationals voting in the election", Ukraine's interior minister Arsen Avakov said.
Twitter planning to ban cryptocurrency ads
The policy will go into effect in two weeks, following similar moves by Facebook and Google to restrict ads for digital coins. Google will ban online advertisements promoting cryptocurrencies and initial coin offerings from June.
Sunday marks exactly four years since President Vladimir Putin, who is seen as a virtual certainty for a fourth term, signed a treaty declaring Crimea part of Russia after taking control of the former Soviet territory following the ouster of a Russian-backed president in Ukraine's capital Kiev.
"Only persons with a diplomatic status will be allowed to access these institutions", Avakov said in a post on his Facebook page Friday.
The statement also criticized Russian Federation for its "illegal attempt to annex Crimea in contravention of global law", and warned of "significant consequences" for Moscow's actions, adding that Moscow had "a clear choice to make". "By its actions, the Russian Federation has violated worldwide law and basic principles of relations between countries", the Latvian Ministry of Foreign Affairs said in a statement marking the anniversary.
The Ministry of Foreign Affairs calls on Latvian citizens to pay attention to travel restrictions imposed by Ukraine in the Crimean Peninsula annexed by the Russian Federation.
