A rescue operation is underway to save nine miners missing after an explosion at a pit in Ukraine's eastern Donetsk region. The blast was triggered by methane gas.
Rescue teams are trying to reach the trapped men. Mine rescue officials say the site was operating illegally.
The explosion happened 300 metres below ground and caused the shaft to collapse and damaged ventilation systems.
The mine is in a small town 90 kilometres north of the regional capital of Donetsk and less than half that distance from Slaviansk where pro-Russian separatists have taken up arms.
