USA's præsident havde inviteret Tyrkiets leder Recep Tayyip Erdogan til Det Hvide Hus, hvor de begge kritiserede Syrien for kemisk krigsførsel.

Barack Obama:
'We have seen evidence of the use of chemical weapons inside of Syria. It is important for us to make sure that we're able to get more specific information about what exactly is happening there.'

'And as we gather more evidence and work together, my intention is to make sure that we're presenting everything that we know to the international community as an additional reason, an additional mechanism, for the international community to put all the pressure that they can on the Assad regime, and to work with the opposition to bring about that political transition.'
