PRESIDENT OBAMA:..Of course, we discussed Syria and the appalling violence being inflicted on the Syrian people. Together, we’re going to continue our efforts to increase pressure on the Assad regime, to provide humanitarian aid to the long-suffering Syrian people, to strengthen the moderate opposition, and to prepare for a democratic Syria without Bashar Assad.

And that includes bringing together representatives of the regime and the opposition in Geneva in the coming weeks to agree on a transitional body which would allow a transfer of power from Assad to this governing body. Meanwhile, we’ll continue to work to establish the facts around the use of chemical weapons in Syria, and those facts will help guide our next steps. (..)

PRIME MINISTER CAMERON:..So we welcome President Putin’s agreement to join an effort to achieve a political solution. The challenges remain formidable, but we have an urgent window of opportunity before the worst fears are realized. There is no more urgent international task than this. We need to get Syrians to the table to agree a transitional government that can win the consent of all of the Syrian people. But there will be no political progress unless the opposition is able to withstand the onslaught, and put pressure on Assad so he knows there is no military victory. So we will also increase our efforts to support and to shape the moderate opposition.
