UNITED NATIONS - The United States said on Wednesday Syria's new pledge to halt all fighting by dawn on Thursday holds "little if any credibility" and that the caveats placed by President Bashar Assad's government on the ceasefire are worrying.
US Ambassador to the United Nations Susan Rice said the commitment - made by Syria in a letter to Kofi Annan, envoy of the United Nations and Arab League - could not be construed as complying with Annan's six-point peace plan.
"The burden remains squarely on the Syrian regime and not the opposition in the first instance to meet its obligations in full and visibly under the Annan plan," Rice told reporters.
"The caveats in the letter are worrying and yet again cast into doubt the credibility of any such commitments but nothing casts more doubt on the credibility of the commitments than the fact that commitments have been made and made and made and broken and broken and broken," she said.
In the letter to Annan on Wednesday, Syria said it reserves the right to respond to any attack by "armed terrorist groups."
