ROUGH CUT (NO REPORTER NARRATION)
The White House warned Russia on Friday (April 18) that Moscow would face tougher sanctions if it failed to abide by a new international deal on Ukraine or moved to send Russian forces into eastern Ukraine.
"Those costs and sanctions could include targeting very significant sectors of the Russian economy," Susan Rice, President Barack Obama's national security adviser, told reporters.
She said Washington was watching very closely to see whether Russia met its obligations to use its influence to get pro-Russian separatists in eastern Ukraine to disarm and abandon public buildings they had seized.
Separatists said on Friday they were not bound by the agreement brokered by the United States, Russia, Ukraine and the European Union in Geneva on Thursday (April 17).
