The United States has seen "no signs yet" that the Syrian government is abiding by its international commitments, the White House said on Monday.
"[This] is obviously quite unfortunate," presidential press secretary Jay Carney told reporters a day after Damascus appeared to back away from the cease-fire agreement meant to end the violence there.
The government of Syrian President Bashar al-Assad said on Sunday that the cease-fire agreement calling for its forces to pull out of towns and villages by Tuesday was "wrong" and that it needs written guarantees from the armed opposition groups that they will also lay down their weapons, The Wall Street Journal reported.
The initial agreement, brokered by Kofi Annan, the United Nations and Arab League's special envoy to end the conflict, called for forces loyal to Assad to pull out by Tuesday, and for all parties to stop fighting by 6 a.m. on Thursday to pave the way for negotiations over Syria's political future.
"We will see what happens come April 10," Carney said, after which the U.S. will then look to Annan to assess the Syrian government's behavior.
