Ukraine crisis: Protecting the gates at Sevastopol military base

Pro-Russian soldiers apparently tried to seize another Ukrainian military base outside Sevastopol overnight but no shots were fired and they pulled back.

The unidentified forces used an army truck to ram the gates at the entry to the base. Two journalists were attacked and beaten during the standoff.

Ben Brown reports from inside the air defence post where Ukrainians have taken steps to prevent another attempted invasion.
