A student asked the Prime Minister "what is your next step in Arab Spring countries?"
He replied: "I am a supporter of the Arab Spring". He said that all countries should be free to follow their own paths, but that he wanted to encourage the "building blocks of democracy" such as rule of law, women's rights and a free press.
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.
