The International Monetary Fund's board signed off on a $17 billion two-year aid program for Ukraine on Wednesday to help the former Soviet republic's economy recover after months of turmoil.

The IMF aid will allow the immediate disbursement of $3.2 billion to Kiev, and unlock further credits from other donors of about $15 billion, intended to help Ukraine stabilize its economy amid its worst civil turmoil since independence in 1991.

IMF Managing Director Christine Lagarde admitted the program faces geopolitical risks, along with uncertainty about the government's ability to carry out the politically unpopular measures necessary to get its finances in order.
