President Barack Obama will hold a secure video conference with European leaders to discuss the crisis in Ukraine Tuesday.

The White House said Obama would confer with leaders from Britain, France, Germany, Italy and the European Union on a conflict that has now claimed more than 6,000 lives.

Washington and its European allies have accused Russia of fueling the conflict by sending troops and weapons across the border and propping up rebels.

Moscow denies the charges.
