KIEV, Ukraine (AP) -- Police in the Ukrainian city of Odessa say 31 people have died as the result of a building fire that broke out during a clash between pro-Russia demonstrators and supporters of the central government in Kiev.
The statement said the fire broke out in a trade union building on Friday, but did not give details on how it started.
Until now, Odessa, a key port on Ukraine's southern Black Sea coast, had largely been free of the unrest that is gripping eastern parts of Ukraine in recent weeks.
Today, the government launched an offensive against insurgents in Slovyans. Ukraine's acting president claims "many" insurgents have been killed or wounded. Russia says the move has "destroyed" the two-week-old agreement aimed at cooling the situation.
