The deepening crisis in Ukraine is taking a fresh turn this morning with the country's government saying its troops are carrying out an operation in the eastern town of Kramatorsk.
Ukraine's interior minister says its forces have seized control of a TV tower.
The town is near Slavyansk which saw a violent day yesterday - at least 31 people were also killed when a building was set on fire in Odessa.
