The stand-off in Ukraine's Crimea region between Moscow and Kiev is escalating. Russian military helicopters have been seen in the skies, armoured personnel carriers are on the roads and Crimea's pro-Russian leader has taken control of the military and the police. Reports from Simferopol on how people there are reacting to the developments.

The latest diplomatic talks were prompted after Russian President Vladimir Putin gained permission from parliament to send troops to the Crimea. It's not yet known when or if that will happen, but more armed men are appearing in the region. Reports from Moscow.
