Poroshenko made the comment after claiming that "9,000 Russian soldiers" are present in Ukrainian territory. On Saturday, a day before Poroshenko's statement, Estonia's Foreign Minister Marina Kaljurand said that Russia does present a military threat for the country.
"Is it possible that he attacks Finland: Yes. That he attacks the Baltic states: Yes. The Black Sea States: Yes," Poroshenko said in the interview.
Poroshenko's claim that Russia would attack the Baltic states was contradicted by Estonia, whose foreign minister said the previous day that Russia does not pose a military threat to the Baltic country.
"At this moment we do not see a direct threat for NATO from the direction of Russia," Estonia's foreign minister said.
Kaljurand made the statement in response to a report from Sweden, which claims that Russia could attack the Baltic states.
