The Obama administration has called for the restoration of calm in Kyrgyzstan, where the opposition claims to have taken control of the government.
The White House said Thursday President Barack Obama has been closely following the events in the Central Asian nation and urges that calm be restored in a manner consistent with democratic principles and human rights.
A White House statement said the U.S. deplores the use of deadly force by both security forces and demonstrators and continues to be concerned by looting and disorder.
