Ukraine's acting government today issued an arrest warrant for President Viktor Yanukovych, in the aftermath of last week's deaths of more than 80 people in clashes between protesters and police.

After signing an agreement Friday to form a unity government, Yanukovych fled the capital for eastern Ukraine, where he has a strong base of support. Officials say he has released his official security detail, and drove off to an unknown location.
