BBC: 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. After Ukrainian forces recaptured an airfield outside Kramatorsk on Tuesday, armoured vehicles appeared in the centre of the town early on Wednesday. BBC journalists witnessed civilians, at least some of whom appeared to be local people, challenging soldiers, who were also blocked by a crowd a few kilometres outside the town.
