Ukraine: Military column seized by pro-russian militants in Kramatorsk
Pro-Russian militants in eastern Ukraine have seized six Ukrainian armoured vehicles, the defence ministry in Kiev says.
Reports say the occupants were disarmed after the vehicles were blockaded by locals in the city of Kramatorsk.
The incident comes a day after the military began an operation to remove pro-Russian protesters from public buildings across eastern Ukraine.
Meanwhile, Nato is increasing activity in member states bordering Russia.
