27 February 2014 Last updated at 23:22 GMT

Ukraine's interim government has warned Russia against interfering in the country's political crisis, after Russia conducted military drills near the border.

In the Crimea region, armed men seized the area's parliament building and hoisted a Russian flag on the roof, in a show of defiance to the country's new leaders.

Meanwhile ousted President Viktor Yanukovych has vowed to give a press conference on Friday from Russia, 70 miles from the Ukrainian border.
