Western and Arab nations stepped up verbal pressure on Syrian President Bashar al-Assad on Sunday, mistrusting his acceptance of a plan to end a year of bloodshed, but stopped short of arming rebels or fully recognising an opposition council.
In a sign of impatience with what they see as stalling by Assad, the "Friends of Syria" urged peace envoy Kofi Annan to set a timeline for next steps, including a return to the UN Security Council, if the Syrian leader fails to halt bloodshed.
Violence has raged on unabated despite Annan's mediation. The Syrian Observatory for Human Rights reported at least 41 people killed across Syria on Sunday, including five in bombardment of pro-opposition districts in Homs.
In a final communique, the 83-nation group said Assad did not have an open-ended opportunity to meet his commitments to Annan, who is acting for the United Nations and Arab League.
"The regime will be judged by its deeds rather than its promises," the communique said. Security Council members China and Russia and Syria's ally Iran were among countries that stayed away from the conference in Istanbul. Assad has accepted, but not yet implemented, Annan's six-point peace plan, which calls for the military to cease fire, withdraw from towns and cities, and allow humanitarian access. "We will not let the Syrian regime misuse another opportunity, which is the last chance for the situation in Syria," Turkish Foreign Minister Ahmet Davutoglu told a news conference after the meeting he hosted.
The "Friends of Syria" recognised the opposition Syrian National Council (SNC) as a legitimate representative of all Syrians, and "noted" it as the main opposition interlocutor with the international community - wording that fell short of full recognition of a group hampered by chronic disunity.
The group made no mention of supporting or arming the rebel Free Syrian Army (FSA), as advocated by some Gulf Arab states, but said it would "continue to work on additional appropriate measures with a view to the protection of the Syrian people".
Hard-line Gulf states are likely to interpret the phrase as a licence to fund, if not arm, the FSA, while the United States and others will see it as allowing supplies of non-lethal equipment to the loosely organised armed opposition to Assad.
US Secretary of State Hillary Clinton told the conference her government was supplying "communications equipment that will help activists organise, evade attacks by the regime and connect to the outside world" and was "discussing with our international partners how best to expand this support". Clinton berated Assad for not acting on Annan's peace plan. "Nearly a week has gone by, and we have to conclude that the regime is adding to its long list of broken promises," she said.
"There is no more time for excuses or delays ... This is a moment of truth," Clinton told a news conference later.
Western powers have been wary of military intervention in Syria, but Davutoglu sounded an alarm bell, comparing the situation there to the plight of Bosnia in the 1990s.
