Ukraine is claiming Russia's launched a missile with greater range into one of its cities.  

It's claiming an intercontinental ballistic missile has been used, but CNN reports two western officials have said it was another type of ballistic missile.  

Europe correspondent Vincent McAviney told Ryan Bridge the US is disputing the claim and Russia's saying nothing.

He says it comes with escalation this week, with missiles being provided by the US given permission to fire into Russia.
