ISTANBUL -- A coalition of more than 70 partners, including the United States, pledged Sunday to send millions of dollars and communications equipment to Syria's opposition groups, signaling deeper involvement in the conflict amid a growing belief that diplomacy and sanctions alone cannot end the Damascus regime's repression.

The shift by the U.S. and its Western and Arab allies toward seeking to sway the military balance in Syria carries regional risks because the crisis there increasingly resembles a proxy conflict that could exacerbate sectarian tensions.

The Syrian rebels are overmatched by heavily armed regime forces.

The summit meeting of the "Friends of the Syrian People" follows a year of failed diplomacy that seems close to running its course with a troubled peace plan led by UN-Arab League envoy Kofi Annan.

Indeed, U.S. Secretary of State Hillary Rodham Clinton and other participants at the conference in Istanbul uniformly expressed concern that Annan's plan might backfire, speculating that Syrian President Bashar Assad would try to manipulate it to prolong his hold on power.

Clinton said she was waiting for Annan's report to the UN Security Council Monday on the status of his peace plan.

"There cannot be process for the sake of process. There has to be a timeline. If Assad continues as he has, to fail to end the violence, to institute a cease-fire, to withdraw his troops from the areas he has been battering . . . then it's unlikely he is going to ever agree," she said.
