Russia troops tightened their grip on Crimea as huge political rallies were held across the country.
ITV News Europe Correspondent Emma Murphy reports from Donetsk in eastern Ukraine:
Eastern Ukraine's Babuchkas, older women who have worked hard to raise families, are said to be the real power in these parts of the world.
Ukranian military commander told ITV News the Russian men "have come to protect us. So why are their guns pointing towards our base?"
Fear is shaping events in Crimea, the multi-ethnic peninsula that finds itself at the heart of a tussle between great powers.
