US Secretary of State John Kerry said on Saturday that supporters of the Syrian opposition will step up military and other aid in a bid to end an "imbalance" on the ground in President Bashar al-Assad's favour.
Mr Kerry, speaking at a conference of foreign ministers in Qatar, said that the United States remained committed to a peace plan that includes a conference in Geneva and a transitional government picked both by Mr Assad and the opposition.
The rebels need more support "for the purpose of being able to get to Geneva and to be able to address the imbalance on the ground," he said.
"The United States and other countries here - in their various ways, each choosing its own approach - will increase the scope and scale of assistance to the political and military opposition," he added.
