Ukraine oligarch put on the spot as rebels nibble at his empire

DONETSK Ukraine (Reuters) - The clanging of repairs to tanks and heavy armoured vehicles rings out from a factory in eastern Ukraine that is owned by the country's richest man but was taken over by pro-Russian rebels.

Rinat Akhmetov's Corum company says it has nothing to do with the current work at the factory, where captured army vehicles are re-marked and men fix tank tracks, clean cannons and apply extra layers of armour.
