I am standing with the Syrian border just behind me and every night 500 refugees are fleeing the most appalling persecution and bloodshed to come to safety and frankly what we have done so far is not working. The history of the country behind me, Syria, is being written in the blood of its own people.
We have had two failed resolutions at the United Nations, two envoys, countless ceasefires and there are 30,000 people who have died. One of the first things I want to do with the newly-elected president is talk about how we can do more for refugees here on the border, more pressure on the United Nations, more pressure on this dreadful regime behind me in Syria, more to help the opposition.
Prime Minister David Cameron said Syria's President Bashar al Assad should face "full international justice" for his "appalling crimes".
The Prime Minister has faced questions about his promotion of arms deals during a three-day tour of the Gulf region that started today.
