The number of Russian troops on the border has risen to 30,000, an increase of about 10,000 from last week. U.S. President Barack Obama said during an official trip to Brussels that while it concerns him, Russia has a right to be on Russian soil.
"Right now they are on Russian soil. And if they stay on Russian soil, we oppose what appears to be an effort at intimidation, but Russia has a right, legally, to have its troops on its own soil. I don't think it's a done deal. And I think Russia's making a series of calculations," Obama said in a press conference.
Obama has also called for all NATO nations to increase their presence in Eastern Europe. In May, Denmark will be sending 6 F-16 fighter jets to Ukraine as a "signal" to the Baltic countries that NATO stands with them.
"This is a signal especially to the Baltic countries that we stand shoulder to shoulder with them and of course also a signal to Russia that we take NATO seriously." said Denmark's Foreign Minister Martin Lidegaard.
