WASHINGTON (AFP) - The United States on Wednesday called the deadly violence on the streets of the Ukrainian capital "completely outrageous" and renewed its appeal to President Viktor Yanukovych to de-escalate the situation.

Clashes in Kiev between police and anti-government protesters that have claimed 26 lives are "completely outrageous" and "have no place in the 21st century", Deputy National Security Advisor Ben Rhodes told reporters on Air Force One.
