At least seven people have been killed in the eastern Ukrainian city of Mariupol.
The government says its troops responded when activists tried to take over the police headquarters.
Most of the dead are thought to be pro-Russian activists.
The BBC's Richard Galpin spent some of the day in Mariupol.
