Oxfam has said it is "appalled" that the number of Syrian refugees has reached two million, adding that the humanitarian response is "stretched to the limit".
Enough is enough. A generation of Syrians is paying too high a price in this conflict. They have been seriously let down by the international community, which has failed to prioritise a political solution to the conflict.
That must change. World leaders - especially President Obama and President Putin - must ensure the long-promised peace talks take place as soon as possible.
