Ukraine crisis: Armed men patrol Crimean airports

There are more signs of tension in Ukraine after armed men began patrolling airports in the Crimean capital Simferopol and Belbek International airport in the Black Sea port of Sevastopol.

It was not immediately clear who the men were, nor the reason for their presence at the airports.

It comes a day after pro-Russian armed men stormed Crimea's local parliament.

Tensions have heightened in the autonomous region since the ousting of President Viktor Yanukovych last week.
